摘要： PURPOSE:To obtain a color liquid crystal display element which does not have dependence on visual angles, and has good dynamic stability and a long life, by enclosing a nematic liquid crystal contg. a dichroic colorant and a quaternary ammonium salt in a space between substrates subjected to a vertical orientation treatment. CONSTITUTION:In a color liquid crystal display element in which a nematic liquid crystal having a negative dielectric anisotropy and contg. a dichroic colorant and an ionic substance of a quaternary ammonium salt is enclosed in a space between two substrates and either or both of these substrates is/are subjected to a vertical orientation treatment, a compd. of the formula (wherein R1-R4 are each alkyl, fluoroalkyl, at least one of R1-R4 is a 7-20C alkyl; X is halogen anion, nitro-substd. benzoate anion) is used as said quaternary ammonium salt. By using a display mode of a dynamic scattering mode in this color liquid crystal display element, positive display with high display contrast can be obtd. without using a polarizing plate.

摘要： PURPOSE:To provide the titled display element which gives positive display with high display contrast and is capable of lowering and steepening threshold value, by adding a dichroic dye, an ionic material and an optically active material to a host liquid crystal having a negative dielectric anisotropy. CONSTITUTION:Glass substrates 1, 2 are opposed to each other at a given distance therebetween. Each of transparent electrodes 3, 4 of, e.g., In2O3 is provided on an opposing side of each of the substrates 1, 2. A liquid crystal 5 is enclosed in a space between the both electrodes. Said liquid crystal 5 is obtd. by adding an optically active material such as a compd. of the formula to a host liquid crystal having a negative dielectric anisotropy and further adding a dichroic dye and an ionic material thereto. The opposing surfaces of the substrate 1, 2 are previously subjected to a vertical orientation treatment. Hence, no color is developed when no voltage is applied to the electrodes. When voltage is applied to the electrodes 3, 4, the dipole moment of the liquid crystal molecule is inclined to rotate in the direction of the electrical field, the molecules are revolved by the action of the ionic additive and the dichroic dye as well as the liquid crystal molecules are brought into a disturbed state. Thus, a positive display which has high contrast and is easy to observe from any directions can be obtd. By adding the optically active material, it is possible to steepen threshold value at a low voltage.

摘要： PURPOSE:To decrease reflected light and to prevent coloring while voltage is off by forming a reflection film via about >=0.3mm. spacing on the outer side of one of the transparent insulating substrates of a liquid crystal display element which forms white blanked colorless patterns while the voltage is off. CONSTITUTION:Liquid crystals 4 contg. dyes 5 are interposed between two sheets of transparent insulating substrates 3 formed with oriented films 1 and transparent electrodes 2 on the inside surfaces, whereby a display element is formed. Dichromatic dyes 5 and nematic liquid crystals 4 are used for the element which forms white blanked colorless patterns while voltage is off. here, the element may color slightly according to the conditions formed by the films 1. In such a case, a reflection plate 8 is formed via a transparent film 7 or a spacing 10 of about >=0.3mm. on the outer side of one substrate 3. Then the light incident from the other substrate 3 is reflected to decrease the reflected light. Thus, the coloring while the voltage is off is prevented andthe images having good contrast are formed.

摘要： PURPOSE:To eliminate the dependency of a nematic type or white teller type guest-host liq. crystal display device on the visual angle and to obtain a clear display by making the orienting direction of the liq. crystal molecules and the dichromatic dye molecules of the device vertical to the observing direction. CONSTITUTION:In a nematic type guest-host color liq. crystal display device having orienting films 12, 22 rubbed in the horizontal direction (shown by arrows) (a), a white teller type one having orienting films 12, 22 rubbed in the horizontal direction (b) and a white teller type one having an orienting film 12 rubbed in the vertical direction and an orienting film 22 rubbed in the horizontal direction (c), the rubbing directions are prescribed so as to allow the tilt angle theta of liq. crystal molecules 4 to satisfy theta=alpha when each device is observed from the side of the substrate having the film 12 and to maximize the absorption of light in liq. crystal molecules and dichromatic dye molecules when the device is seen from a direction having an angle alpha to a direction just above the observation surface. Thus, since the device is not generally seen from a place just above the observation surface, a clear display can be seen.

摘要： PURPOSE:To inject a liq. crystal into a liq. crystal cell at high speed without deforming the cell by placing the crystal and the cell in a vessel isolable from the air, removing the air, immersing the injection hole of the cell in the crystal, and regulating the internal pressure of the vessel to atmospheric pressure or above with gaseous N2 or the like. CONSTITUTION:A liq. crystal 3 and a liq. crystal cell 1 are placed in a vessel 4 the inside of which is isolable from the air, and the air in the vessel 4 including the inside of the cell 1 is removed to form a vacuum. The injection hole 2 of the cell 1 is then immersed in the crystal 3, and gaseous nitrogen is introduced into the vessel 4 to regulate the internal pressure of the vessel 4 to atmospheric pressure or above, e.g., to 3 atm. The crystal 3 enters the cell 1 from the hole 2 under the pressure of the gaseous nitrogen, and the cell 1 is thoroughly filled with the crystal 3 in a short time such as 1.5min. During the injection no deformation is caused in the cell 1.

摘要： PURPOSE:To prevent the reflection of light due to the unevenness of a colored layer and to keep a display bright and easy to see by forming a transparent resin layer on the colored layer fromed on a polarizing plate so as to make the uneven back side of the colored layer even. CONSTITUTION:The transparent resin layer 20 is formed by printing on the back side of a colored layer 15 formed by printing on the back side of a polarizing plate 13. The resin layer 20 makes the uneven back side of the colored layer 15 even, and the back side of the layer 20 is much smoother than that of the layer 15. When the thickness of the resin layer 20 is 3-10mum, the uneven back side of the colored layer 15 can be made even, the layers, 20, 15 transmit well light emitted from a light source 14 for illumination, and a display on a liq. crystal cell 11 can be observed clearly. The quantity of light transmitted is increased by 65-70% by forming the resin layer 20.

摘要： PURPOSE: To decrease the reflection of light before and behind a color temp. correcting filter layer and to obtain a distinct display by printing directly the color temp. correcting filter layer on a colored layer to be printed on a polarizing plate.
CONSTITUTION: The colored layer 15 is provided by printing on the rear surface of the polarizing plate 13 and the color temp. correcting filter layer 20 is directly printed on the rear of the layer 15. The layer 20 has the effect of increasing the color temp. of an illuminating light source 14 of, for example, about 2,500°K to ≥3,000°K, more preferably 3,500W5,000°K. The layer 20 is obtd. by adding a coloring agent into a transparent resin such as vinyl chloride resin or vinyl chloride/acryl copolymer resin. The light of light source 14 transmits well the layer 20 and the layer 15 if the layer 15 and the layer 20 are printed to 5W10μm thickness. The distinct observation of the display of a liquid crystal cell 11 is thus made possible.
