A display device, includes a substrate; first to fourth subpixels sequentially arranged on the substrate; a first power line on a left side of the first subpixel and shared by the first and second subpixels; a sensing line between the second subpixel and the third subpixel and shared by the first to fourth subpixels; a second power line on a right side of the fourth subpixel and shared by the third and fourth subpixels; and a first data line on the left side of the first subpixel, a second data line on a right side of the second subpixel, a third data line on a left side of the third subpixel, and a fourth data line on the right side of the fourth subpixel. The first and second power lines and the sensing line are disposed on a layer different from the first to fourth data lines.
