摘要： A display device includes a display panel having a display area and a peripheral area. The display device includes a circuit having a comparator, and first and second sense wires disposed in the peripheral area and connected to the circuit. The comparator compares a first output signal output from the first sense wire and a second output signal output from the second sense wire to generate a comparison result. The circuit determines whether a defect is present in the display device based on the comparison result.
