Abstract
The present invention relates to a display device, and particularly, to a display device using a semiconductor light emitting device. The display device includes a substrate including an electrode, a plurality of light emitting devices assembled on the substrate, and a color conversion part stacked on the plurality of semiconductor light emitting devices and converting a color. Specifically, the color conversion part includes: a porous layer, a wavelength conversion layer, and a reflective layer, wherein the wavelength conversion layer is disposed between the porous layer and the reflective layer, and the porous layer is formed of an electro-polishable porous terminal. A surface of the reflective layer includes a first region and a second region surrounded by the first region, the second region has roughness higher than that of the first region, and a plurality of first protrusions are disposed in the second region.
