摘要： PURPOSE:To enhance the reliability of connection by conductive material. CONSTITUTION:The external connecting terminals formed on a lower transparent substrate SUB 1 and inter-substrate connecting terminals CTM are connected via drawing out wirings INT. The inter-substrate connecting terminals CTM and common transparent pixel electrodes ITO 2 formed on an upper transparent glass substrate SUB 2 are connected by a conductive paste material CDP. The inter-substrate connecting terminals CTM are formed out of first conductive films (transparent conductive films) d1. The parts corresponding to the conductive paste material CDP parts of light shielding films BM are provided with openings PPH. These openings PPH are formed larger than the inter-substrate connecting terminals CTM. Conductive beads CDB which are formed by plating the surfaces of spherical polymer resins with gold and are mixed with an epoxy thermosetting resin are used as the conductive paste materials CDP.

摘要： PROBLEM TO BE SOLVED: To provide a high quality liquid crystal display device in which degradation in light transmittance caused by reduction in size and processing dispersion of electrode gaps is suppressed, and consequently, high luminance is provided and no irregularity exists in the luminance. SOLUTION: When a threshold value voltage VC applied between a pixel electrode PX and a counter electrode CT is expressed as follows: VC=(πL/ d)×(K2/ε0|Δε|)1/2 where L is a gap between a pair of the electrodes, d is a cell gap, K2 is a twist elastic constant of liquid crystals, ε0 is dielectricity in vacuum, Δε is the dielectric anisotropy of the liquid crystals (a difference in dielectricity between in long and in short axis directions), the electrodes PX and CT are arranged with an electrode gap in which a relative liquid crystal transmittance during the time of white display becomes 85 to 95% of the maximum liquid crystal transmittance when a maximum liquid crystal driving voltage is applied between the electrodes PC and CT.

摘要： PROBLEM TO BE SOLVED: To obtain a liq. crystal display which can display uniform images without exhibiting unevenness in display in the whole display region by specifying the amt. of a specific benzil compd. contained in a liq. crystal compsn. sealed into a liq. crystal panel. SOLUTION: This liq. crystal display has a liq. crystal panel which is prepd. by sealing liq. crystal compsn. into the space between two facing substrates provided that the liq. crystal compsn. contains at least one benzil compd. represented by the formula (wherein R and R' are each H or CH3S-) in an amt. of about 1 γ/g or lower. The display is produced by injecting a liq. crystal compsn. contg. at least one benzil compd. represented by the above-mentioned formula into the space between two facing substrates, applying an ultraviolet- curable sealant contg. a photoreaction initiator to the sealing port of the liq. crystal compsn., and irradiating the applied sealant with ultraviolet rays in such an integrated quantity of radiated ultraviolet rays that the amt. of the benzil compd. which is formed by the ultraviolet irradiation and is dissolved out is about 1 μg/g or lower.

摘要： PROBLEM TO BE SOLVED: To obtain the sufficient and specified advancing length of a sealing material in the liquid crystal sealing port of a liquid crystal display element and eventually to improve the reliability of the sealing part of the liquid crystal display element. SOLUTION: This device is constituted to seal liquid crystals to the inner side of the sealing material SL from the sealing port INJ formed in part of the sealing material S1 disposed to a frame shape on the marginal circumference of a transparent substrate SUB 1 constituting the liquid crystal display element and to seal the sealing port INJ by the sealing material EC. In such a case, gate wirings GL extend near to the end side of the substrate SUB 1 near the sealing port INJ and the respective outermost contour lines of the gate wirings GL have the angle with the perpendicular direction of the end sides, thereby forming zigzag folded patterns.
