Abstract: A display apparatus including a light-emitting device is discussed. A device planarization layer, a plurality of micro-lenses, a color filter, a black matrix and an optical lens can be disposed on the light-emitting device. The color filter and the optical lens can overlap the light-emitting device. The black matrix can be disposed side by side with the color filter between the light-emitting device and the optical lens. An upper surface of each micro-lens toward the color filter can include a lens groove. The lens groove of each micro-lens can have a conical shape with a concave side. Thus, in the display apparatus, luminance and efficiency according to a viewing angle can be improved.

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.
