Abstract

A display apparatus includes: a circuit board including a driving circuit; and a pixel array disposed on the circuit board and including pixels, each of the pixels having a plurality of sub-pixels. The pixel array includes: a semiconductor stack, a conductive partition structure and wavelength conversion portions. The semiconductor stack includes LED cells respectively constituting the plurality of sub-pixels. Each of the LED cells includes at least an active layer and a second conductivity-type semiconductor layer. The conductive partition structure is provided between sub-pixel spaces, respectively overlaps the LED cells on the semiconductor stack, and is provided as a first electrode. The wavelength conversion portions are respectively disposed on the sub-pixel spaces.
