Abstract

Display panel and display device are provided. The display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a driving transistor and an initialization transistor. The initialization transistor is configured to provide an initialization signal for a preset node. The preset node is a gate of the driving transistor, or an anode of the light-emitting element. The pixel circuit includes an oxide semiconductor transistor and a silicon transistor. An active layer of the oxide semiconductor transistor includes an oxide semiconductor, and an active layer of the silicon transistor includes silicon. The pixel circuit includes a first pixel circuit and a second pixel circuit. The first pixel circuit includes a first initialization transistor. The second pixel circuit includes a second initialization transistor. An active layer of the first initialization transistor is connected to an active layer of the second initialization transistor through a first connection wire.
