The present disclosure provides a display panel and a method for testing for occurrence of a crack in the display panel. The display panel includes a panel body, a ground line, a first ground connecting portion, a first testing portion, a second ground connecting portion, a second testing portion, a first switch and a second switch, the ground line surrounds the display region, the first ground connecting portion and the first testing portion are parallel connected to one end of the ground line, the second ground connecting portion and the second testing portion are parallel to another end of the ground line, the first switch is electrically connected between the first ground connecting portion and one end of the ground line, the second switch is electrically connected between the second ground connecting portion and another end of the ground line.

Display panel and method for testing for occurrence of crack in display panel

A display panel and a method for testing for an occurrence of a crack in a display panel are provided. The display panel includes a panel body, a ground line, a first ground connecting portion, a first testing portion, a second ground connecting portion, a second testing portion, and a switch. By measuring a voltage, a resistance, or a current between the first testing portion and the second testing portion, an open circuit in the ground line and a crack in a non-display area can be detected. Therefore, difficulty of confirming if a crack occurs in the display panel is reduced.
