Abstract
A display panel and a display device are disclosed in the present application. The display panel includes a plurality of data lines, a Demux circuit, a plurality of signal lines, and at least one signal adjusting trace. Wherein the signal adjusting trace and corresponding signal lines are disposed in different layers and intersect with each other, along a second direction, the signal adjusting trace is configured to output a voltage adjusting signal at least before a next controlling signal is output by controlling traces, to adjust a voltage value of a next data voltage output by the signal line within an output period of the voltage adjusting signal.
