Abstract: The present disclose provides a display panel and a display device. The display panel includes a display area, a non-display area surrounding the display area, at least one notch, a cathode layer, a peripheral bus, and shift registers. A first non-display area and a second non-display area are oppositely disposed, and a third non-display area and a fourth non-display area are oppositely disposed. A cathode layer includes a cathode connection portion. A peripheral power bus is connected to the cathode connection portion in a cathode contact region. A first cathode contact region and first shift registers are located in a notched non-display area and are overlapped with each other. A second cathode contact region is located in the fourth non-display area. A width of the first cathode contact region in a first direction is less than a width of the second cathode contact region in a second direction.

Abstract: A display panel and a display device are provided. A display region is divided into a first display region and at least one second display region smaller than the first display region. The display panel includes compensation lines and to-be-compensated lines located in the display region. Each compensation line is electronically connected with one to-be-compensated line, an orthographic projection of the compensation line on the substrate is overlapped with an orthographic projection of one power supply line on the substrate, and a capacitance is formed between the compensation line and the power supply line, or each compensation line is electronically connected with one power supply line, an orthographic projection of the compensation line on the substrate is overlapped with an orthographic projection of one to-be-compensated line on the substrate, and a capacitance is formed between the compensation line and the to-be-compensated line.
