Liquid crystal display device
First Claim
1. A liquid crystal display comprising, in sequence:
- a light source device that emits a parallel light beam;
a back surface-side polarizer;
a liquid crystal cell;
a display surface-side polarizer; and
a light diffusion layer,wherein the liquid crystal display further comprises;
a selective light-shielding layer between the display surface-side polarizer and the light diffusion layer so that the selective light-shielding layer shields light that is generated by being depolarized and scattered in the liquid crystal cell and travels in a direction that is different from a direction in which the parallel light beam travels,the light source has a half-value angle of the parallel light beam being 20°
or less,an absorption axis of the back surface-side polarizer is orthogonal to that of the display surface-side polarizer,the selective light-shielding layer comprises light-shielding parts and light-transmitting parts, and the light-shielding parts and the light-transmitting parts are arranged in stripes so that a direction orthogonal to a width direction of the stripes becomes parallel to an absorption axis of the display surface-side polarizer, andthe liquid crystal cell contains liquid crystal molecules aligned in a homeotropic alignment.

Abstract
A liquid crystal display being capable of improving the contrast ratio in the front direction thereof is provided. A liquid crystal display 100 of the present invention includes, in sequence: a light source device 14 that emits a parallel light beam; a back surface-side polarizer 16; a liquid crystal cell 13; a display surface-side polarizer 11; and a light diffusion layer 15. The liquid crystal display 100 further includes: a selective light-shielding layer 12 between the display surface-side polarizer 11 and the light diffusion layer 15 so that the selective light-shielding layer 12 shields light that is generated by being depolarized and scattered in the liquid crystal cell 13 and travels in a direction that is different from a direction in which the parallel light beam travels.
