Abstract

An organic light emitting display (OLED) device having an organic light emission unit, the organic light emitting unit including a first electrode layer on a substrate, a second electrode layer on the first electrode layer, and an organic layer between the first electrode layer and the second electrode layer, the OLED device including a first auxiliary electrode layer between the organic layer and the first electrode layer. The organic light emission unit is divided into first, second, and third pixel units. Each of the first, second, and third pixel units includes a second auxiliary electrode layer between the organic layer and the first auxiliary electrode layer. The second auxiliary electrode layers of the first, second and third pixel units are formed to have different thicknesses respectively, so that light beams emitted from the first, second and third pixel units can be provided with a resonance effect.
