Abstract
A display panel and a display device are provided. The display panel includes: a pixel circuit, a light-emitting element and an initialization signal line. The initialization signal includes an enabling level and a non-enabling level, and the enabling level of the initialization signal is configured to initialize a target node of the pixel circuit. The initialization signal line extends in a first direction, and includes a first initialization signal line and a second initialization signal line. The pixel circuit includes a first pixel circuit connected to the first initialization signal line and a second pixel circuit connected to the second initialization signal. A screen refresh cycle of the display panel includes a first stage, the first initialization signal line transmits the enabling level, and the second initialization signal line transmits the non-enabling level, in the first stage.
