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, wherein the first driver circuit is configured to provide a first control signal for the pixel circuit, and the first driver circuit comprises a plurality of stages of first shift registers cascaded with each other in a first direction;
• wherein the display panel further comprises a first signal line group, wherein the first signal line group is connected to the first driver circuit, and a first signal line in the first signal line group overlaps the first shift registers;
• and
• 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 and the first direction intersect, wherein W11<W12;
• wherein the second power signal bus comprises a first sub-signal line and a second sub-signal line, the first sub-signal line and the second sub-signal line are disposed in different layers, and the first sub-signal line is connected to the second sub-signal line through a first via, the first sub-signal line at least partially overlaps the driver circuit, and a width of the first sub-signal line is larger than a width of the second sub-signal line;
• wherein the display panel further comprises a first power signal line, the first power signal bus provides a first power signal for the pixel circuit through the first power signal line, the first power signal line is located in a display region of the display panel, and
• wherein the width of the first sub-signal line is larger than a width of the first power signal line.
