Abstract:
1. A display apparatus comprising: a display panel; a plurality of light sources disposed below the display panel to emit light and arranged spaced apart from each other; and an optical plate provided between the display panel and the light sources, wherein the optical plate comprises: first convex patterns and second convex patterns performing a light diffusion function and formed on the first base region and the second base region, respectively, wherein the first uniform thickness is a thicknesses from a bottom of the base to a valley of the first convex pattern, and the second uniform thickness is a thicknesses from the bottom of the base to a valley of the second convex pattern, wherein the first convex patterns have linearly extending apexes extending in a first direction and the second convex patterns have linearly extending apexes extending in a second direction substantially perpendicular to the first direction, and wherein the first convex patterns have a first height, the second convex patterns have a second height, and a difference between the first uniform thickness and the second uniform thickness is equal to or larger than the first height.
