Abstract
An OLED display includes a substrate member, a plurality of pixel electrodes on the substrate member, a pixel defining layer on the substrate member, the pixel defining layer including a pixel defining part and a plurality of light scattering spacer parts, the pixel defining part including a plurality of openings corresponding to and exposing the pixel electrodes, and the light scattering spacer parts protruding upward from the pixel defining part away from the substrate member, an organic light emitting layer on the pixel electrodes, a first common electrode on the organic light emitting layer, at least a portion of the first common electrode being on the pixel defining layer to overlap the light scattering spacer parts, a transmissive film on the first common electrode, and a second common electrode on the transmissive film.
