  • Publication number: 20220208933
    Abstract: A display device includes a substrate on which a display area including a plurality of pixels and a non-display area surrounding the display area are defined, a first voltage line disposed on the substrate in the non-display area, where the first voltage line provides a first voltage to the pixels, a second voltage line disposed on the substrate in the non-display area, where the second voltage line provides a second voltage to the pixels, and a first demux circuit area and a second demux circuit area disposed on the substrate in the non-display area, where the first demux circuit area and the second demux circuit area transmit data signals to the pixels. The first voltage line passes an area between the first demux circuit area and the second demux circuit area.
