Abstract
A display apparatus includes a circuit substrate with driving circuits and first bonding electrodes, and a pixel array having LED cells, each of the LED cells including first and second conductivity-type semiconductor layers with an active layer therebetween, second bonding electrodes on the first bonding electrodes, wavelength converters on the LED cells, an upper semiconductor layer on the LED cells and having a partition structure surrounding side snakes of the wavelength converters and separating the wavelength converters, a first reflective electrode on the side surfaces of the LED cells, spaced from the LED cells by a passivation layer, and extending between the LED cells, second reflective electrodes on the lower surfaces of the LED cells and connected to the second conductivity-type semiconductor layers, a common electrode on at least one side of the LED cells, and a pad electrode outside the LED cells and electrically connected to the driving circuits.
