1. A liquid crystal display apparatus comprising a liquid crystal panel and a viewer-side polarizing plate stacked on a light exit surface of the liquid crystal panel,
wherein the viewer-side polarizing plate comprises a patterned layer comprising a first resin layer and a second resin layer having different indexes of refraction; and a patterned portion comprising multiple engraved optical patterns and a flat section between adjacent engraved optical patterns of the multiple engraved optical patterns is formed at an interface between the first resin layer and the second resin layer, wherein the liquid crystal display apparatus satisfies the following Equation 1 and the engraved optical patterns have an aspect ratio of 0.3 or more:
10≤P2/P1≤30,
where P1 is a pitch (unit: μm) of the patterned portion, and P2 is a width (unit: μm) of a pixel of the liquid crystal panel in a same direction as a maximum width of an engraved optical pattern of the adjacent engraved optical patterns, the pitch of the patterned portion being defined as a sum of the maximum width of the engraved optical pattern and a maximum width of the flat section, wherein, in Equation 1, P2 is from 150 μm to 950 μm.
