Abstract:
1. An organic light emitting diode (OLED) display comprising: a substrate; a first electrode on the substrate; a first emission layer on the first electrode; a second emission layer on the first emission layer; a second electrode on the second emission layer; a light emitting assistance layer positioned between the first emission layer and the second emission layer only at a first pixel region and the light emitting assistance layer not positioned between the first emission layer and the second emission layer at a second pixel region and a third pixel region different from the first pixel region; and a color transformation matrix positioned in the third pixel region neighboring the second pixel region and configured to convert a wavelength of a light emitted from the first emission layer and the second emission layer, wherein the color transformation matrix is only positioned in the third pixel region and not positioned in the first pixel region and the second pixel region.
