Display panel

A display panel, comprising:

• a substrate;
• and
• a sub-pixel disposed on the substrate, wherein the sub-pixel comprises a reflective region and a light transmissive region, the light transmissive region is disposed in the reflective region, and the sub-pixel further comprises:
• a switch device disposed in the reflective region;
• a first electrode completely disposed in the reflective region and electrically connected to a drain of the switch device, wherein the first electrode is formed of a metal layer;
• a transparent electrode disposed on the first electrode and in the reflective region and the light transmissive region, wherein the transparent electrode is electrically connected to the first electrode, the transparent electrode has a first length in a first direction and a second length in a second direction, and the first direction and the second direction are different;
• a reflective electrode disposed on the transparent electrode and in the reflective region, wherein the reflective electrode is electrically connected to the transparent electrode, the reflective electrode has a third length in the first direction and a fourth length in the second direction, the third length is greater than the first length and the fourth length is greater than the second length;
• and
• an electrode disposed between the transparent electrode and the first electrode,
• wherein the reflective electrode comprises an opening, and the opening is corresponded to the light transmissive region of the sub-pixel.
