Liquid crystal display apparatus

A liquid crystal display apparatus comprising:

• a liquid crystal panel;
• a viewer-side polarizing plate stacked on a light exit surface of the liquid crystal panel;
• and a first optical sheet and a second optical sheet sequentially stacked on a light incidence surface of the liquid crystal panel such that the first optical sheet is between the second optical sheet and the light incidence surface of the liquid crystal panel,
• wherein the viewer-side polarizing plate comprises a polarizer and a contrast ratio or viewing angle-enhancing layer,
• the liquid crystal panel has a horizontal direction corresponding to a long side thereof and a vertical direction corresponding to a short side thereof,
• the first optical sheet has a plurality of first optical patterns on a light exit surface thereof, an angle of a longitudinal direction of the first optical patterns relative to the vertical direction of the liquid crystal panel being from −10° to +10°,
• an angle of the longitudinal direction of the first optical patterns relative to a light absorption axis of the polarizer is from −10° to 10° or from 80° to 100°,
• the first optical patterns have a height of 30 μm to 50 μm, a width of 40 μm to 150 μm, and an aspect ratio of 0.3 to 0.9,
• the second optical sheet has a plurality of second optical patterns on a light exit surface thereof, and
• the second optical patterns have a width of 40 μm to 150 μm, a height of 30 μm to 50 μm, and an aspect ratio of 0.3 to 0.9;
• wherein the contrast ratio or viewing angle-enhancing layer comprises a non-patterned contrast ratio-enhancing layer, the non-patterned contrast ratio-enhancing layer comprises a single layer comprising a matrix;
• and optically anisotropic materials aligned in the matrix, and a difference in index of refraction between the optically anisotropic materials and the matrix is 0.15 to 0.25.
