Abstract: Dummy filters which are irrelevant to displaying are arranged in a matrix consecutively with respect to color filter lines or columns close to a pouring opening. Although spacers move toward the pouring opening when the substrates are pressed for attachment, the moving spacers are stopped by and gathered around the dummy filters. This can prevent a pixel area from being adversely affected due to a light-less phenomenon.

Abstract: A surface-type illumination device suitable for providing backlight in a liquid crystal display is disclosed. For example, an L-shaped fluorescent light can be used as an illuminant and mounted next to two edges of a substantially rectangular light guide plate. The corner of an edge portion between the two edges is removed. The fluorescent light, the length of whose illuminating portion is long, is positioned with an appropriate gap from the light guide plate allowing for illumination with high brightness and low power consumption. Consequently, when the illumination device is used in a color liquid crystal display, appropriate backlight with high brightness can be obtained. Moreover, because the influence of the temperature from the illumination device is small, a stable color display can be achieved.

Abstract: A liquid crystal modulation element and a projection-type liquid crystal display apparatus are provided for maintaining color purity and improving luminance of an image. Microlenses each provided for every three pixel electrodes condense color rays of B, R and G incident at mutually different angles and have the rays enter the pixels of the respective colors. Trimming filters are each provided on the respective pixel electrodes for intercepting rays leaking onto the own pixel electrode of the color rays to enter the neighboring pixel electrodes. As a result, a reduction in color purity due to color mixture is prevented even if the incident divergence angles of the color rays entering a liquid crystal panel are large. Since the incident divergence angles may be relatively large, the amount of diaphragming in the optical projection system may be reduced. A large quantity of light is thereby obtained.

Abstract: The present invention attempts to overcome irregular display deriving from a variation in resistance among wiring electrodes or periodicity of resistances. At least two output terminals of a driving IC chip and one electrode are linked, whereby the width of a wiring electrode can be made twice larger or more. Consequently, the variation in resistance among wiring electrodes is minimized. Furthermore, if driving IC chips are placed at both ends of belt-shaped electrodes, a difference in voltage between the right and left sides of a display screen will not occur. A difference in display state between the right and left sides of the display screen can be resolved (FIG. 3).
