Abstract: A liquid crystal display includes a first data line, a second data line, and a pixel electrode. The first data line transmits a first data voltage when the second data line transmits a second data voltage. A polarity of the second data voltage is opposite to a polarity of the first data voltage. The pixel electrode includes a first branch, a second branch, a third branch, and a fourth branch. The first branch is between the first data line and the second data line. The second branch neighbors the first branch in a first direction and overlaps the second data line. The third branch neighbors the first branch in a second direction and overlaps the first data line. The fourth branch neighbors the third branch in the first direction, neighbors the second branch in the second direction, and is between the first data line and the second data line.
