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.
