Abstract

In a liquid crystal display, first and second substrates are provided opposing each other with a liquid crystal layer held between them, the outer surface of the first substrate serves as a light scattering surface having a light scattering characteristic, and a reflector including an irregular reflection surface is provided on the light scattering surface so that the reflection surface is on the light scattering surface side.

Claims (7)

1. A liquid crystal display comprising:

a pair of opposing transparent substrates having a liquid crystal layer held therebetween;

a reflector having an irregular reflection surface provided on one of the transparent substrates; and

a light scattering element disposed between the reflection surface and the liquid crystal layer,

wherein light reflected by the reflection surface is scatterd by passing through the light scattering element and a haze of said light scattering element is in a range from 15% to 30%.

2. A liquid crystal display according to claim 1 , wherein the light scattering element is disposed between said one of the transparent substrates and the reflection surface.

3. A liquid crystal display according to claim 1 , wherein the light scattering element is a light scattering film.
