Abstract
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.
