Abstract: The present disclosure discloses a display panel and a detecting method thereof. By providing at least one resistance sensor in a bending region, an extending direction of the resistance sensor is perpendicular to an extending direction of an axis for bending and overlaps with the axis for bending. By electrically connecting the resistance sensor to a detecting circuit, a change of the resistance value of the resistance sensor can be reflected as a change of voltage.
