Abstract:
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 substrate and the second substrate, wherein the compensation layer includes at least a first optical path changing pattern and a second optical path changing pattern, wherein the second optical path changing pattern is configured to refract an incident light ray that is incident at a predetermined angle of incidence on the second optical path changing pattern, wherein the first and second optical path changing patterns have different refractive indexes and are alternately arranged in a direction substantially in parallel to the surface of the second base substrate, wherein the first optical path changing pattern and the second optical path changing pattern contact each other, and wherein a contact surface of the first optical path changing pattern and the second optical path changing pattern is inclined with respect to the 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.
