摘要： A reflective liquid crystal display apparatus realizing a bright image display without using a backlight is provided. In this reflective liquid crystal display apparatus, a reflecting electrode having a scattering property and a directional property is manufactured using a small number of steps. A pattern of unevenness, such as a polygonal pattern, a cylindrical pattern, and the like, is formed on an insulating substrate utilizing a material layer formed for composing switching devices. By causing the unevenness of the pattern to influence the surface contour of the reflecting electrodes, it becomes possible to give both a scattering property and a directional property to the surface of the reflecting electrodes.

摘要： In a backlight using an LED, area control is performed such that the backlight is lit only in the bright area of the screen and the backlight is not lit in the dark area. The temperature change in the light emission efficiency of the LED is large. The temperature of the lit LED is high in area control, so that when a completely gray screen is displayed after the area control, the light emission efficiency of the LED decreases in the previously illuminated area, resulting in the occurrence of uneven brightness. The present invention prevents the uneven brightness of the screen in area control, by reducing the temperature change in the light emission efficiency of the LED to 5% or less, and more preferably 3% or less, in a temperature range of 50° C. to 90° C.

摘要： In a liquid crystal apparatus in which a white light of a fluorescent tube corresponding to a linear light source repeats plural times of diffusions and reflections between a reflection sheet and a diffusion plate, and is thereafter input as a back light to a liquid crystal panel corresponding to a display screen, an object of the invention is to make it possible to secure a brightness uniformity even if the liquid crystal apparatus is thinned. It is possible to prevent a brightness unevenness caused by a short distance from the reflection sheet to the diffusion plate, by preventing a deformation (a deformation which is convex toward the fluorescent tube) of the diffusion plate due to a thermal expansion of the diffusion plate caused by a heat generation of the fluorescent tube, by arranging at least one pin mold hold so as to support a portion near an approximately center of the diffusion plate.
