Abstract

A display panel includes a display area including at least one through hole and an annular non-display area between the through hole and the display area enclosing the through hole. The annular non-display area includes: at least two annular blocking dams, a through-hole crack detecting line, and a connecting portion. The annular blocking dams enclose the through hole and are mutually nested. Adjacent annular blocking dams are spaced at a predetermined distance. The through-hole crack detecting line comprises an input wiring portion, an output wiring portion and a winding portion. The input wiring portion and the output wiring portion are connected through the winding portion. The input wiring portion and the output wiring portion extend to the display area. The winding portion is around the edge of the through hole. The connecting portion is between the annular blocking dams and connecting some areas of the annular blocking dams.
