A display device may include a plurality of pixel circuits disposed adjacent to each other, the plurality of pixel circuits including a plurality of active patterns disposed to correspond to the pixel circuits, respectively. Each of the active patterns includes a first initialization channel region to which an initialization voltage is applied, a second initialization channel region to which the initialization voltage is applied, and a third initialization channel region to which the initialization voltage is applied, the second initialization channel region of each of the active patterns is connected to the first initialization channel region of the adjacent active patterns, and a first end region of the third initialization channel region is connected between the first initialization channel region and the second initialization channel region.
