Abstract: The present disclosure relates to display devices, and more specifically, to a display device with a sensor circuit capable of sensing the presence or absence of an abnormality in a signal line located in a bending area. Through these, a display device is provided that enables an accurate check to be performed for the presence or absence of an abnormality, such as a crack, or the like in signal lines located in the bending area, and thus, has a normal bending structure without defects.
