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.

Abstract: Discussed is a display device for improving both transmittance and efficiency of light that is transmitted through a light-emitting unit and a transmissive unit due to a phase difference of π at an interface between an organic layer and an optical compensation layer of the display device.
