Abstract
Provided are a display panel and a display device. The display panel includes a pixel driver circuit. The pixel driver circuit includes a light-emitting module, a drive transistor and at least one light-emitting control transistor. The drive transistor, the light-emitting control transistor and the light-emitting module are connected in series between a first power supply signal terminal and a second power supply signal terminal, and at least one of the drive transistor or the light-emitting control transistor is a first double-gate transistor. The first double-gate transistor includes a first gate, a second gate and a first source, and the second gate is electrically connected to the first source.
