摘要： A reflector for a reflection-type LCD device is provided, which reflects efficiently incident light to the viewer's side and that suppresses the change of color tone. The reflector comprises a roughened surface having a protrusion pattern. The protrusion pattern gives inclination angle to the surface according to a specific distribution where a first component with an inclination angle value of 0° is 15% or less in area and a second component with an inclination angle value from 2° to 10° is 50% or greater in area. The protrusion pattern gives a variation range of chromaticity coordinates (x, y) on a chromaticity diagram dependent on an angle of view. The variation range is limited in a circle on the chromaticity diagram. The circle has a radius of approximately 0.05 and a center at a point corresponding to white color.

摘要： In a semi-transmissive liquid crystal display device, the thickness of liquid crystal layer in the reflective region can be adjusted by controlling the film thickness of the organic insulating film for reflection and the film thickness of the color layer for reflection. Furthermore, the thickness of liquid crystal layer in the transmissive region can be adjusted by controlling the film thickness of the organic insulating film for transmission and the film thickness of the color layer for transmission. Since the thicknesses of liquid crystal layer in the reflective region and that in the transmissive region can be adjusted, the reflectance in the reflective region and the transmittance in the transmissive region can each be set at the most appropriate values.

摘要： A liquid crystal display device includes a liquid crystal cell, first and second polarizers disposed outside the liquid crystal cell, first and second retardation plates arranged between the first and second polarizers, and the liquid crystal cell, and optical layers arranged between the first and second retardation plates and the liquid crystal cell. The first and second retardation plates have lagging axes perpendicular with each other. The first polarizer has an absorption axis inclining by about 45 degrees relative to the lagging axis of the first retardation plate, and inclining by about 90 degrees relative to an absorption axis of the second polarizer. The absorption axes of the first and second polarizers are angularly deviated such that characteristic of a viewing angle in the liquid crystal display device is rendered symmetric, relative to a symmetry axis about which liquid crystal is aligned in different directions.

摘要： Color filters of R, G and B consisting of a negative resist film are simultaneously exposed by use of a photomask intercepting light for the regions connected to the transparent pixel electrodes after the source electrodes. Then, the color filters are simultaneously developed. Since the color filters consist of a negative resist film, the regions of the color filters corresponding to the light-intercepted regions, that is, the regions connected to the transparent pixel electrodes after the source electrodes are removed by the development, so that openings are formed.
