摘要： A display device is disclosed including a display area having a non-rectangular shape, in which a first area and a second area are joined. The second area is smaller than the first area in a first direction, and the second area is adjacent to the first area in a second direction orthogonal to the first direction. A non-display area is adjacent to the second area in the first direction and adjacent to the first area in the second direction. A plurality of pixel circuits is arranged in the display area in the first direction and the second direction, avoiding the non-display area. A plurality of first control lines and second control lines are grouped into control line assemblies arranged such that control line assemblies of different types belonging to each of the plurality of groups are adjacent to each other, in order to simplify load adjustment.

摘要： Provided is a display device including a plurality of pixels at least one of which has a first transistor and a light-emitting element. The first transistor includes a gate electrode, a gate insulating film over the gate electrode, an oxide semiconductor film over the gate insulating film, and a first terminal and a second terminal electrically connected to the semiconductor film. The second terminal is electrically connected to the light-emitting element. A region in which the first terminal overlaps with the gate electrode can be smaller than a region in which the second terminal overlaps with the gate electrode.
