发明名称 LCD with diffuser having particular haze value and diffuser-reflector distance, and reduced parallax
摘要 Above a TN liquid crystal panel 140 , there is provided an upper polarizing plate 130 , and below it, there are sequentially provided a color filter 150 , a lower polarizing plate 160 , a light diffusion plate 170 , a reflection polarizing plate 180 , a backlight 190 , and a light reflection plate 200 . And the relationship between the haze value H of the light diffusion plate 170 and the distance between the light diffusion plate 170 and the light reflection plate 200 is set so as to satisfy the formula: H>=-200d+140, whereby it is possible to sufficiently diffuse incident light 111 passing through the light diffusion plate 170 and reaching the light reflection plate 200 ; in the case of black and white display, a reduction in parallax is achieved, and in the case of color display, the reflected light can be made white.
