Abstract: A display device includes a data line, a vertical transmission line and a horizontal transmission line. The data line extends in a first direction and is arranged in a second direction on a display area divided into upper and lower display areas, and is connected to pixels. A vertical transmission line extends in the first direction on the display area. The vertical transmission line receives a ground power supply voltage from an upper side of the display area to transfer the ground power supply voltage to the pixels, and receives a data voltage from a lower side of the display area. A horizontal transmission line extends in the second direction on the display area and is arranged in the first direction. The horizontal transmission line is connected to the vertical transmission line and the data line on the lower display area to transfer the data voltage to the data line.
