Abstract

A display panel and a display device are provided. The display panel includes pixel circuits. Each pixel circuit includes a driving transistor, a data writing circuit, a light-emitting control circuit, a threshold compensation circuit and a bias adjustment circuit. The driving transistor includes a gate electrically connected to a first node, a first terminal electrically connected to a second node, and a second terminal electrically connected to the third node, and is configured to generate a driving current. The third node is connected to a light-emitting element through the light-emitting control circuit. The bias adjustment circuit is configured to provide a signal of a bias adjustment signal terminal to the second node under control of a signal of a first scanning signal terminal in such a manner that a bias state of the driving transistor is adjusted.
