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.
