Abstract: A display panel and a display device are disclosed. The display panel includes M columns of pixel circuits, M negative power supply lines, and M positive power supply lines. A negative power supply line and a positive power supply line are respectively arranged on both sides of a column of pixel circuits. An input end of the negative power supply line is arranged opposite to an input end of the positive power supply line. A voltage in the positive power supply line gradually decreases, and a voltage in the negative power supply line gradually increases. This reduces differences in power supply voltages delivered to each pixel circuit.
