Display panel and display device

A display panel, comprising:

• a base substrate, comprising a display region and a peripheral region surrounding the display region;
• a first common electrode bus line, a second common electrode bus line and a conductive connection layer which are disposed on the base substrate,
• wherein both the first common electrode bus line and the second common electrode bus line are located in the peripheral region and respectively disposed on two adjacent sides of the display region;
• the first common electrode bus line comprises a main body part and a branch part extending from an end of the main body part to a side away from the display region, the main body part extends along a first direction, and the branch part is located on a side of the main body part away from the display region;
• the second common electrode bus line extends along a second direction, the second common electrode bus line comprises a first end proximate to an end of the main body part, an orthographic projection of the end of the main body part on the base substrate does not overlap an orthographic projection of the first end on the base substrate, and the first direction intersects the second direction;
• in the peripheral region, the conductive connection layer is electrically connected with the branch part of the first common electrode bus line through a first via hole structure, and the conductive connection layer is electrically connected with the first end of the second common electrode bus line through a second via hole structure, and an orthographic projection of the first via hole structure on the base substrate at least partially overlaps with an orthographic projection of the branch part on the base substrate.
