Abstract
A pixel structure includes a plurality of data lines and a common line. The common line overlaps each data line, and is coupled with each data line to respectively form a first coupling capacitor, a second coupling capacitor, a third coupling capacitor, a fourth coupling capacitor, a fifth coupling capacitor, and a sixth coupling capacitor. The third coupling capacitor is smaller than the second coupling capacitor, and the fifth coupling capacitor is smaller than the fourth coupling capacitor.
