Abstract: A display device includes a substrate which includes a display area and a non-display area, a pixel unit which is provided in the display area and includes a plurality of pixel columns, and data lines which are respectively connected to the pixel columns and apply data signals to the pixel columns. The non-display area includes a fanout area, a bent area, and a pad area which are sequentially arranged. The respective data lines are disposed on different layers in the fanout area and the pad area. A resulting display device can reduce resistance deviation between data signals in a first data line and a second data line, thereby reducing vertical line defects.
