Abstract: A display device includes insulating layers, a light-emitting element, and a pixel circuit electrically connected to the light-emitting element. The pixel circuit includes a first transistor. The first transistor includes a metal oxide semiconductor pattern including a source region, a drain region and a channel region disposed between the source region and the drain region, a first gate disposed on the metal oxide semiconductor pattern and overlapping the channel region in a plan view, and a metal oxide pattern disposed on the first gate.
