Abstract: Provided is a display device having a structure in which a hole area in which camera sensors or the like are disposed is included in an active area of a display panel. Data lines among a plurality of data lines bypassing the hole area are disposed on different layers to prevent an increase in the load of data lines, through which green subpixels are driven. Degradations in the luminance of subpixels disposed around the hole area and driven through the data lines bypassing the hole area are prevented. The uniformity of luminance around the hole area is improved.
