Abstract: A display device and a method of fabricating the same are disclosed, the display device includes a first metal layer on a substrate; light emitting elements emitting light of a first color, each of the light emitting elements having a first end contacting the first metal layer; an insulating layer disposed on the first metal layer and including holes exposing a second end of each of the light emitting elements facing the first metal layer; and a light conversion layer disposed in at least one of the holes and overlapping the light emitting elements. The light conversion layer converts the light of the first color emitted from the light emitting elements into light of a second color.
