An organic light emitting display for minimizing light from entering the pixels is provided. The organic light emitting display includes a substrate including a pixel region and a pixel-separating region between pixel regions; a first insulating layer on the substrate; a first electrode in a pixel region and on the first insulating layer; a pixel definition layer overlapping an edge region of the first electrode and in a region between the pixel region and the pixel-separating region; an organic light emitting layer on the first electrode and the pixel definition layer; a second electrode on the organic light emitting layer; and a black matrix between the first insulating layer and the pixel definition layer and extending outwardly past an edge region of the pixel definition layer into the pixel-separating region, such that the pixel definition layer is separated from the first insulating layer.
