Abstract: A display device includes: scan lines extending in a first direction; data lines extending in a second direction intersecting the first direction and receiving data voltages; first driving voltage lines extending in the second direction and receiving a first driving voltage; second driving voltage lines extending in the second direction and receiving a second driving voltage different from the first driving voltage; and pixels connected to the scan and data lines. Each of the pixels includes first, second, and third subpixels arranged in the first direction. The first driving voltage lines and the second driving voltage lines are alternately arranged in the first direction. A location of the first driving voltage line in a first pixel differs from a location of the second driving voltage line in a second pixel. The second pixel is adjacent to the first pixel in the first direction.
