Title:
DISPLAY APPARATUS USING SEMICONDUCTOR LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/135441
Kind Code:
A1
Abstract:
The present invention relates to a display apparatus and, particularly, to a display apparatus using a semiconductor light-emitting device. The display apparatus, according to the present invention, comprises: a substrate including an electrode; a plurality of semiconductor light-emitting devices assembled on the substrate; and a color conversion unit stacked on the semiconductor light-emitting device so as to convert color. Specifically, the color conversion unit comprises a porous layer, a wavelength conversion layer, and a reflective layer, the wavelength conversion layer is arranged between the porous layer and the reflective layer, and the porous layer can be made of an electro-polishable porous material. Furthermore, the surface of the reflective layer has a first region and a second region surrounded by the first region, the second region has higher surface roughness than the first region, and a plurality of first protrusions is arranged in the second region.
