Patent ID: 8018141

Claim:
An organic light emitting display device comprising: a substrate; an insulation layer on the substrate; a pixel electrode on the insulation layer; a pixel defining layer on the insulating layer and having an opening for exposing a portion of the pixel electrode, and comprising: an intermediate portion adjacent to the pixel electrode; and a peripheral portion spaced from the intermediate portion to form a trap on at least one side of a periphery of the pixel electrode, the trap extending from the intermediate portion to the peripheral portion and comprising a surface of the insulation layer between the peripheral portion and the intermediate portion, an organic functional layer on at least the exposed portion of the pixel electrode and including at least an emission layer; and a counter electrode on the organic functional layer, wherein a top portion of the peripheral portion is below the organic functional layer, and wherein the intermediate portion is disposed between the opening and the trap and the peripheral portion, and wherein the intermediate portion has a height smaller than a height of the peripheral portion.
