A display panel and a display device are provided. The display panel includes a light-emitting element, a pixel circuit, and a comparison module. The pixel circuit includes a driving transistor and a first transistor, and the first transistor and the driving transistor are connected to each other in series. The comparison module is coupled to a gate of the first transistor, and the comparison module is configured to compare a voltage value of a comparison signal and a voltage value of the reference signal to generate a control signal, and to provide the control signal to the gate of the first transistor. An operating phase of the pixel circuit includes a light-emitting phase. During the light-emitting phase, the comparison signal is a constant voltage signal, and a voltage of the reference signal changes over time in at least one period.
