Abstract: A display device includes a display panel that includes a display area and a first peripheral area adjacent to the display area. The first peripheral area includes a bendable region extending across the display panel and a plurality of signal lines partially included in the bendable region. The plurality of signal lines includes a first and second group adjacent to each other in the bendable region. The first group includes two or more first signal lines that transmit signals of a first polarity. The second group includes two or more second signal lines that transmit signals of a second polarity different from the first polarity. The first and second group are separated by a first interval, and signal lines within the first or second group are separated by a second interval. The first interval is greater than the second interval.

Abstract: 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.
