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.
