Abstract: A display device is disclosed that includes a base layer, a light-emitting element, and a pixel circuit. The pixel circuit includes a first transistor, and the first transistor includes a metal oxide semiconductor pattern, a first gate having a plurality of conductive layers, and a gate insulation pattern. The uppermost layer among the plurality of conductive layers is divided into a first part adjacent to a drain region, a second part adjacent to a source region, and a third part between the first part and the second part. An upper surface of each of the first part and the second part may form a step with an upper surface of the third part. A sum of the widths of the upper surfaces of the first part and the second part may be smaller than the width of the upper surface of the third part.
