摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive liquid crystal display device which is widened in the permissible range of the unequal cell thicknesses of TN positive type liquid crystal display elements, increased in yield, free from the unequal colors of projected images, and has high quality, by unifying the cell thicknesses unequally. SOLUTION: The TN positive type liquid crystal display elements are used by combining the elements having unequal cell thicknesses which are respectively partially low with respect to a reference cell thickness and the elements having unequal cell thicknesses which are respectively partially high with respect thereto. When the projected images of the TN positive type liquid crystal display elements 11 of R color and the TN positive type liquid crystal display elements 12 of B color are laterally reversed with respect to the projected images of the TN positive type liquid crystal display elements 13 for G color, the projected images of the TN positive type liquid crystal display elements 11 of R color and the TN positive type liquid crystal display elements 12 of B color are combined in comparison with the regions line symmetrical with the TN positive type liquid crystal display elements 13 for G color. As a result, the excellent projected images free from the unequal colors are obtd. even with the TN positive type liquid crystal display elements which have the asymmetrical unequal cell thicknesses which are heretofore regarded defective.

摘要： PROBLEM TO BE SOLVED: To widen an allowable range of irregular cell thickness so as to enhance yield and to eliminate the color irregularity of a projected picture so as to obtain high image quality at low cost by setting the irregular cell thickness of plural liquid crystal display elements so that the cell thickness at a center part may be smaller than that at a peripheral part. SOLUTION: The irregular cell thickness of plural liquid crystal display elements is set so that the cell thickness at the center part may be smaller than that at the peripheral part. Then, the TN positive type liquid crystal display element where the cell thickness at the center part is smaller than that at the peripheral part and the TN positive type liquid crystal display element where the cell thickness thereat is larger are classified. At such a time, it is desirable to make the level of the irregular cell thickness at the center part as even as possible. For example, the difference of a specified value between the center part and the peripheral part is combined at 0.02 step. The TN positive type liquid crystal display elements of a color R and a color B are compared with a linearly symmetric area of the TN positive type liquid crystal display element of a color G with respect to an inverted plane 14 (for example, a 1a of the display elements of the colors R and B is compared with a 4a of the display element of the color G), and classified and combined so that the difference of average cell thickness is

摘要： PURPOSE:To provide the liquid crystal display device which is bright, is high in contrast, is free from unequal display and has uniform and high image quality by varying the distances between data lines and pixel electrodes and the distances between scanning lines and the pixel electrodes. CONSTITUTION:A rubbing direction is set at the rubbing direction 12 of the lower substrate of transparent substrates and at a rubbing direction 13 of the upper substrate of the transparent substrates by using counterclockwise liquid crystals. The regions where reverse tilt discrimination arises are largest between the data lines 1 and the pixel electrodes 5 and, therefore, the distances a between the data lines 1 and the pixel electrodes 5 are taken large. Both the potential difference and level difference are larger between the data lines 1, 2 and the pixel electrodes 5 than between the scanning lines 3, 4 and the pixel electrodes 5 and, therefore, the electric field intensity in a transverse direction is higher between the data lines 1, 2 and the pixel electrodes 5. The generation where the reverse tilt discrimination arises is larger therebetween as well and, therefore, the distances a, c are set larger than the distances b, d between the scanning lines 3, 4 and the pixel electrodes 5.

摘要： PURPOSE:To obtain a liquid crystal panel which is free from uneven gaps and slippage in assembling so as to reduce unevenness in display, by using the same material for a pair of base plates. CONSTITUTION:A polysilicon thin-film transistor (TFT) 2 is formed in the form of a matrix on a transparent glass base plate 1 as a switching element. Then a light intercepting layer 4 is formed on another transparent glass base plate 3 by a plating method and a color filter layer 5 is formed on the layer 4 by using a photoengraving technique. After forming the layer 5, a common electrode 6 is formed on the layer 5 by a physically depositing method. Thereafter, the pair of glass base plates 1 and 3 are thermocompression-fixed to each other with a spacer 7 and gap forming agent in between them, and thus, a liquid cell is assembled. Then a liquid crystal panel is obtained by enclosing liquid crystal in the cell. When the same material is used for making the pair of base plates in such way, a liquid crystal panel which is free from uneven gaps and slippage in assembling can be obtained. As a result, unevenness in display, such as unevenness in color, contrast ratio, etc., can be reduced.

摘要： PURPOSE:To improve a contrast ratio and a color reproductivity by reversing the input sequence of a color light reflected on a dichroic mirror for synthesizing the respective color lights and a video signal to the source line of an active matrix liquid crystal light value used for transmitted color light. CONSTITUTION:A substrate 2 on which a polysilicon thin film transistor and an opposite substrate having a shading layer are assembled on a liquid crystal cell through a spacer and a gap agent to seal a liquid crystal. When a source driving IC5 gang bonded to a flexible substrate 4 is connected to a liquid crystal panel through a soldering, the liquid crystal light valve for green and the liquid crystal valve for red, blue are vertically opposed. Then, a gate driving IC6 gang bonded to the flexible substrate 4 is mounted in the liquid crystal panel and finally connected to a frame form rigid substrate 1. Thereby, since the respective incident lights can be made incident, the deterioration in the contrast ratio can be prevented, the display characteristic of the respective panels is equal and the color reproductivity is improved.
