Abstract
A display panel is disclosed. The display panel includes a pixel driving circuit. The pixel driving circuit includes: a first transistor, wherein the first transistor and a light-emitting device are series-connected between a first power line and a second power line; and a second transistor, wherein the second transistor and the light-emitting device are series-connected between the first power line and the second power line. A width-to-length ratio of the first transistor is greater than a width-to-length ratio of the second transistor. A display device is further disclosed.
