1. A display panel, comprising:
a drive circuit layer, comprising a common wire;
a color photoresist layer, disposed on the drive circuit layer and comprising a plurality of color filters;
a first passivation layer, disposed on the color photoresist layer;
a common electrode layer, disposed on the first passivation layer and comprising a transparent electrode, wherein the transparent electrode is electrically connected to the common wire;
an insulating layer, disposed on the common electrode layer and the first passivation layer; and
a pixel electrode layer, disposed on the insulating layer and comprising a plurality of pixel electrodes,
wherein a top surface of the transparent electrode facing away from the color photoresist layer is flush with a top surface of the first passivation layer furthest from the color photoresist layer, and the first passivation layer wraps a lateral side of the transparent electrode.
