Display panel and display device
A display panel and a display device comprising a pixel area (A) and a peripheral wiring area, wherein detection switches are arranged between the pixel area (A) and the peripheral wiring area, the detection switches correspond to gate lines (11) and/or data lines (10) of the pixel area (A) one to one, and the detection switches are configured to control connection and disconnection of the pixel area (A) and the peripheral wiring area. In the display panel, it is possible to precisely and quickly detect whether there is a short-circuit or open-circuit defect and the precise position of the defect. It is only required to perform an inching detection on signal lines in a small area during the detection procedure, which saves detection time and improves detection efficiency.
