Abstract: Disclosed is a light emitting display device including a substrate on which first to third sub-pixels are provided, and first to third light emitting devices that are respectively provided in the first to third sub-pixels to emit light of different wavelengths. The first to third light emitting devices each include first to third intermediate layers between a first electrode and a second electrode that face each other. The first to third intermediate layers include a red light emitting layer, a green light emitting layer, and a blue light emitting layer in order on the first electrode, in which the blue light emitting layer of the first intermediate layer has a vertical phase higher than those of the blue light emitting layers of the second and third intermediate layers.

Abstract: An organic light-emitting display device has improved transmittance and UV light reliability by optimizing the thickness and material of a cathode. An organic light-emitting display device comprises an organic light-emitting element on a substrate, the organic light-emitting element including an anode, an organic light emitting layer, and a cathode, an organic layer between the substrate and the organic light-emitting element, and an auxiliary layer adjacent to the cathode and including a material having electron injection ability, such that the influence of UV lights on the OLED device is reduced, thereby improving the efficiency and lifespan of the organic light-emitting element.
