Light emitting diode display
View Patent ↗An organic light emitting diode (OLED) display includes a substrate, a pixel electrode on the substrate, an organic light emitting member on the pixel electrode, a common electrode on the organic light emitting member, a thin film encapsulation member covering the common electrode, a black matrix on the thin film encapsulation member, and an upper protection film on the black matrix. The black matrix has a color filter at a location corresponding to the organic light emitting member. A sum of a thickness of the color filter and a distance between the color filter and the organic light emitting member is smaller than a width of the organic light emitting member.
