[0007] However, since the scattered light 61 scatters the incident light 58, the incident light 58 is reflected in a direction not used to view the liquid crystal screen or in the same direction as the second reflected light 60, resulting in poor utilization efficiency of the light. it is good
[0008] Furthermore, when a color filter is further arranged inside the reflective liquid crystal display device 50 in order to obtain a color image, there may be a pixel whose color is different from that of the color filter through which the incident light 58 passes. and cause color mixing issues on the viewed image

Abstract
In a reflective type liquid crystal display unit which is provided with a reflective plate, there is provided a reflective liquid crystal display unit free from color mixture by preventing color mixing of reflected light is presented. The unit includes a substrate, a reflective layer disposed on the substrate, and a color filter, wherein the reflective layer has a plurality of reflective unit regions each of which has a first reflective surface for reflecting a light in a predetermined direction, and an inclination angle of the first reflective surface is defined so that an incident light which passes through a pixel of a determined color of the color filter to enter the first reflective surface is reflected by the first reflective surface to pass through the pixel of the same color as the color through which the incident light of the color filter has passed.
Description
technical field [0001] The present invention relates to an optical member that reflects incident light in a predetermined direction, a reflective plate, a device using the optical member, and a light reflection method for reflecting incident light in a predetermined direction. Background technique [0002] In recent years, applications of liquid crystal display devices to microcomputers, televisions, word processors, video recorders, and the like have been continuously advanced. On the other hand, in order to further improve the performance of such electronic equipment, it is expected to display liquid crystal images by reflecting externally incident light without using backlight for the sake of miniaturization, energy saving, and cost reduction. Reflective liquid crystal display device. [0003] In such a reflective liquid crystal display device, since the backlight is not used, it is required to efficiently utilize external incident light to illuminate the liquid crystal ...
