Abstract: An array substrate includes: first and second gate lines extending along a first direction; a data line extending along a second direction crossing the first direction, and being insulated from the first and second gate lines; a pixel electrode disposed in a pixel area defined by the data line, the first gate line, and the second gate line; a first auxiliary electrode overlapping the first gate line; and a second auxiliary electrode disposed between the pixel electrode and the second gate line, the second auxiliary electrode being spaced apart from the second gate line. The pixel electrode includes: a first subpixel electrode disposed adjacent to the first gate line, and having first direction size greater than a second direction size; and a second subpixel electrode spaced apart from the first subpixel electrode in the second direction, and having a first direction size greater than a second direction size.
