Abstract
An organic light emitting diode display capable of reducing the shortening of image stacking lifetime caused by the residue of the barrier ribs produced during the forming of the barrier ribs is provided. The display includes: a substrate; a first pixel electrode formed on the substrate; barrier ribs formed on the substrate, and having an opening exposing the first pixel electrode; a second pixel electrode formed on the first pixel electrode; an organic light emitting member formed on the second pixel electrode; an organic light emitting member formed on the second pixel electrode; a common electrode formed on the organic light emitting member; and a thin film encapsulation member covering the common electrode. The width of the second pixel electrode is greater than the exposure width of the first pixel electrode exposed through the opening of the barrier ribs.
