Abstract
An organic light emitting diode (OLED) display includes: a substrate; an organic light emitting element on the substrate; a thin film encapsulation layer covering the organic light emitting element; and a viewing angle compensation layer on the thin film encapsulation layer, wherein the viewing angle compensation layer corresponding to a pixel of the organic light emitting element has a plurality of sub-viewing angle compensation members. Accordingly, in the organic light emitting diode (OLED) display according to an exemplary embodiment, the viewing angle compensation layer is disposed on the thin film encapsulation layer such that optical characteristic changes such as the luminance change and the color change according to the viewing angle may be minimized or reduced.
