Display panel

A display panel, comprising:

• a first substrate;
• a first transistor element and a first scan line both located on the first substrate, wherein the first transistor element is controlled by the first scan line;
• a first insulating layer located on the first substrate;
• a common electrode located on the first insulating layer, the common electrode having a first through hole, wherein the first through hole and the first scan line are partially overlapped;
• a second insulating layer located on the common electrode, the second insulating layer covering the common electrode and partially covering the first through hole;
• a first pixel electrode located on the second insulating layer, wherein the first pixel electrode penetrates through the first through hole, and the first pixel electrode is electrically connected to the first transistor element.
