Abstract
A display apparatus including a heteromorphy lens disposed on a path of light emitted from a light-emitting device, a side surface of the heteromorphy lens toward a first direction has a shape different from a side surface of the heteromorphy lens toward a second direction perpendicular to the first direction, so that light can be condensed in the first direction and diffused in the second direction due to the heteromorphy lens, and the reduction in luminance can be minimized, and the viewing angle can be limited.
