Abstract

Discussed is a display device using a semiconductor light emitting diode disposed on a substrate, a planarization layer stacked on the substrate while defining a hole that is a region in which the semiconductor light emitting diode is disposed, a light-transmitting layer filling the hole, and a reflective layer formed along at least one surface of the substrate and the planarization layer defining an inner surface of the hole, wherein the hole is formed so that a width thereof expands as a distance from the substrate increases.
