Abstract
A unit pixel includes a transparent substrate, a plurality of light emitting devices arranged on the transparent substrate, and an optical layer disposed between the light emitting devices and the transparent substrate and transmitting light emitted from the light emitting devices. The transparent substrate has a concavo-convex pattern on a surface facing the light emitting devices.
