Abstract

A display device can includes a substrate in which a plurality of sub pixels are defined; a light emitting diode disposed in a sub pixel among the plurality of sub pixels on the substrate; and a first transistor which is disposed in the sub pixel and configured to supply a driving current to the light emitting diode. Also, the first transistor can be a high electron mobility transistor (HEMT). Accordingly, the first transistor can have a high electron mobility to supply a high current to the light emitting diode and display a high luminous image.
