Display panel and display device

A display device, comprising a display panel which comprises:

• a driver circuit and a pixel circuit;
• a light-emitting element, wherein the light-emitting element comprises a first electrode and a second electrode;
• and
• a first power signal bus and a second power signal bus;
• wherein the first power signal bus is connected to the pixel circuit, the pixel circuit is connected to the first electrode, and the second power signal bus is connected to the second electrode;
• wherein the second power signal bus at least partially overlaps the driver circuit;
• wherein the driver circuit comprises a first driver circuit and a second driver circuit, wherein the first driver circuit is configured to provide a first control signal for the pixel circuit, the second driver circuit is configured to provide a second control signal for the pixel circuit, the first driver circuit comprises a plurality of stages of first shift registers cascaded with each other in a first direction, the second driver circuit comprises a plurality of stages of second shift registers cascaded with each other, and the first driver circuit and the second driver circuit are located on a same side of a display region of the display panel;
• wherein the display panel further comprises a first signal line group and a second signal line group, the first signal line group is connected to the first driver circuit, and the second signal line group is connected to the second driver circuit;
• wherein a first signal line in the first signal line group overlaps the first shift registers;
• in a second direction, a width of an overlapping region between the first shift registers and the first signal line is W11, a width of an overlapping region between the first shift registers and the second power signal bus is W12, and the second direction intersects with the first direction;
• and
• in the second direction, a total width of an overlapping region between a signal line in the first signal line group and the first shift registers is WS1, a width of an overlapping region between a signal line in the second signal line group and the second shift registers is WS2, and a width of the overlapping region between the second shift registers and the second power signal bus is W22;
• wherein W12>W22≥0, and
• wherein W11<W12, and/or, WS1<WS2.
