Abstract:
A display device includes, in a display area: scan control lines and data signal lines intersecting with each other; subpixels each including a subpixel circuit provided at an intersection of the scan control lines and the data signal lines; and light-emitting elements, one for each of the subpixels. The subpixel circuit includes a drive transistor, a write transistor, and a capacitor that retains a data signal. The write transistor includes a conduction terminal connected to an associated one of the data signal lines, another conduction terminal connected to a first gate terminal of the drive transistor, and a control terminal connected to an associated one of the scan control lines. Each of the light-emitting elements includes a first element electrode, a light-emitting layer, and a second element electrode, the first element electrode being connected to a conduction terminal of the drive transistor. The drive transistor includes a second gate terminal connected to the second element electrode via a contact hole.
