Abstract
A display device includes a substrate on which a plurality of sub-pixels are disposed, a first reflective layer disposed on the substrate, a plurality of LEDs disposed in each of the plurality of sub-pixels on the first reflective layer, a plurality of light conversion layers disposed between the first reflective layer and the plurality of LEDs, and a plurality of second reflective layers covering at least a portion of the plurality of LEDs. Light emitted from the plurality of LEDs is reflected by the plurality of second reflective layers, and light having a wavelength longer than that of the light emitted from the plurality of LEDs is emitted upwardly from the plurality of LEDs.
