Abstract
A display apparatus includes: a circuit substrate; and a pixel array on the circuit substrate and including a plurality of pixels. The pixel array includes: light emitting diode (LED) cells constituting the plurality of pixels, each of the LED cells including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer; wavelength converters on the LED cells; an upper semiconductor layer on the LED cells and having a partition structure; a passivation layer on side surfaces of the LED cells; a first electrode along a region of the LED cells to have a grid shape; second electrodes connected to the second conductivity-type semiconductor layers; and reflective layers between the first electrode and the second electrode along the passivation layer on the side surfaces of the LED cells and having surfaces inclined toward outside of the LED cells.
