Abstract
An OLED display according to an exemplary embodiment includes: a substrate that includes a display area and a non-display area; a pixel circuit that is disposed in the display area; organic light emitting diodes and barrier ribs that are disposed on the pixel circuit; an encapsulation layer that covers the pixel circuit, the organic light emitting diodes, and the barrier ribs; and a color filter that is disposed on the encapsulation layer, wherein the encapsulation layer comprises an edge area that is adjacent to the non-display area in the display area and a center area not directly adjacent to the non-display area and having the edge area disposed therebetween, the color filter comprises a first color filter, a second color filter, a third color filter, and color filter overlapped portions where the first color filter, the second color filter, and the third color filter are overlapped, and the color filter overlapped portions are disposed in areas where the barrier ribs are disposed, and a thickness of the color filter is greater in the edge area than in the center area.
