Abstract: A display device is disclosed that includes a substrate including a display area and a non-display area that at least partially surrounds the display area. The display device further includes a plurality of pixels in the display area. The display device further includes a data drive unit in the non-display area. The display device further includes a plurality of data lines in the display area. The display device further includes a plurality of data link lines disposed in the non-display area that electrically connect together the data drive unit and the plurality of data lines. The display device further includes high-potential voltage link lines in the non-display area that are configured to supply high-potential voltages to the plurality of pixels. The high-potential voltage link lines include a plurality of holes in regions of the high-potential voltage link lines that overlap the plurality of data link lines.
