LIQUID CRYSTAL DISPLAY APPARATUS AND METHOD OF MANUFACTURING THE SAME

摘要

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.

1. A method of manufacturing a display apparatus, comprising:
forming a first substrate including a first base substrate and a plurality of pixel units arranged on the first base substrate; forming a second substrate including a second base substrate facing the first base substrate and a compensation layer arranged on one surface of the second base substrate and facing a major surface of the first substrate wherein the forming of the second substrate comprises: forming a first layer having a first refractive index on the one surface of the second base substrate; patterning the first layer to form a plurality of first optical path changing patterns that are spaced apart from one other along a first direction; and forming a second layer having a second refractive index different from the first refractive index, where the formed second layer has portions thereof interposed between the spaced apart first optical path changing patterns, wherein the first optical path changing pattern and the second optical path changing pattern contact each other, wherein a contact surface of the first optical path changing pattern and the second optical path changing pattern is inclined with respect to the one surface of the second base substrate, wherein the compensation layer includes one homogenous light-passing medium in a first area and includes two light-passing media having different refractive indexes in a second area, and wherein a light transmittance of the first area is larger than a light transmittance of the second area.
