Display panel and display device

A display panel, wherein the display panel comprises a display area, a light emitting unit located in the display area, and a pixel driving circuit for driving the light emitting unit, the pixel driving circuit is connected to a first electrode of the light emitting unit, and the display panel further comprises:

• a base substrate;
• a first power line, disposed in the display area of the display panel, wherein an orthographic projection of the first power line on the base substrate is extended along a first direction;
• a second power line, disposed in the display area of the display panel, wherein an orthographic projection of the second power line on the base substrate is extended along a second direction, the second direction intersects the first direction, and at least a part of the second power line is connected to at least a part of the first power line;
• a common electrode layer disposed at a side of the base substrate, wherein the common electrode layer is used to form a second electrode of the light emitting unit, and the common electrode layer is connected to the first power line and the second power line;
• and
• a data line, an orthographic projection of the data line on the base substrate is extended along the second direction,
• wherein two adjacent second power lines are disposed mirror-symmetrically and two adjacent data lines are disposed mirror-symmetrically.
