Abstract
There is provided a display device. The display device includes a plurality of semiconductor elements disposed on a substrate; a plurality of LEDs disposed on the plurality of semiconductor elements and electrically connected to the plurality of semiconductor elements, respectively; and a plurality of reflectors disposed above the semiconductor elements and each located between every two of the LEDs. The plurality of LEDs may include a plurality of respective light-emitting layers disposed on the plurality of semiconductor elements, and a common electrode disposed on the plurality of light-emitting layers. The reflectors are disposed between the LEDs, so that light emitted from LEDs does not travel toward the side portions of the LEDs but toward the above of the substrate, thereby improving the light extraction efficiency and suppressing color mixture.
