Abstract

Official abstract text for this publication.

The viewing angle of a Liquid Crystal Display (LCD) apparatus is expanded by means of a sampled light redirecting layer, In one embodiment, the sampled light redirecting layer is formed as a compensation layer disposed between a top polarizing plate and the rest of a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal layer interposed therebetween. The compensation layer includes at least two optical path changing patterns disposed in interleaved manner. The two optical path changing patterns have different refractive indexes. As a result of the different refractive indices and shapes of the at least two different optical path changing patterns some of the light rays sampled out of the output of the rest of a liquid crystal display panel are directed in a first direction by means of reflection or refraction and some are directed in a different second direction, thereby improving a side visibility of the display apparatus.

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid crystal display apparatus comprising: a first substrate having a first base substrate and a plurality of pixel units arranged on the first base substrate; a second substrate including a second base substrate and a compensation layer, wherein the second base substrate faces the first base substrate, and wherein the compensation layer is arranged on a surface of the second base substrate; and a liquid crystal layer disposed between the first subs…
