Display panel and common electrode of the same

A display panel, comprising:

• a gate driving device;
• multiple scanning lines, wherein a side of the multiple scanning lines are electrically connected to the gate driving device, and the multiple scanning lines are extended along the row direction and are in parallel to each other;
• multiple pixel electrodes electrically connected to corresponding scanning lines through thin-film transistor;
• a common electrode, wherein the common electrode and the pixel electrode form two electrodes of a pixel capacitor, the common electrode includes multiple main trunk electrodes arranged sequentially along a row direction;
• a common voltage providing unit electrically connected to the multiple main trunk electrodes for providing common voltages to corresponding main trunk electrodes;
• wherein from a side closed to the gate driving device to a side away from the gate driving electrode, in adjacent two main trunk electrodes, a common voltage on a previous main trunk electrode is less than or equal to a common voltage on a next main trunk electrode, and a common voltage of a first main trunk electrode is less than a common voltage on a last main trunk electrode.
