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.

Abstract: Discussed is a light-emitting display device, which emits light unchanged by maintaining a cavity of internal light using reverse cavity characteristics through an optical compensation structure, and achieves high luminance characteristics despite a change in a viewing angle, prevents external light from being reflected, and is excellent in terms of efficiency and lifespan by combining the optical compensation structure with a color filter structure. The optical compensation structure includes at least one first layer having a first refractive index and at least one second layer having a second refractive index greater than the first refractive index, the first layer being thicker than the second layer.
