A display panel for a display device having a backlight module includes a first substrate, a plurality of data lines, a plurality of pixel electrodes, a dielectric layer, and a common electrode. The data lines are disposed substantially in parallel on the first substrate. The pixel electrodes are respectively disposed between the data lines. The dielectric layer covers the pixel electrodes and the data lines. The common electrode is disposed on the dielectric layer, and the common electrode has two first electrode branches, two second electrode branches, and two third electrode branches. The electrode branches are respectively and correspondingly disposed on the both sides of the pixel electrodes. The first electrode branches, the second electrode branches, and the third electrode branches respectively have a first interval, a second interval, and a third interval therebetween. The first interval is larger than the second interval and the third interval.
