Abstract
A display panel and a display device. The display panel comprises: a substrate, a display area (100) provided with at least one light-emitting signal line (E), at least one first reset signal line (R) and sub-pixels arranged in an array, at least one sub-pixel (P1, P2, P3) comprising: a light-emitting device (L) and a pixel circuit. The first reset signal line (R) is configured to provide a reset control signal for the pixel circuit, the light-emitting signal line is configured to provide a light-emitting control signal for the pixel circuit to provide a driving current. For the first reset signal line and the light-emitting signal line E connected to a same pixel circuit, the duration in which the signal of the light-emitting signal line is an invalid level signal is equal to the duration in which the signal of the first reset signal line is a valid level signal.
