A liquid crystal display includes a substrate, first and second pixel groups, a first gate line group comprising first gate lines connected to the pixels of the first pixel group, a second gate line group comprising second gate lines connected to the pixels of the second pixel group, a first data line group connected to the pixels of the first pixel group and comprising first data lines extending in a second direction, and a second data line group connected to the pixels of the second pixel group and comprising second data lines extending in the second direction. Each data line of the first data line group and each data line of the second data line group are connected to each other, and the first and second pixel groups are adjacent in the first direction.
