1. A display panel, comprising:
an array substrate;
a planarization layer, disposed on the array substrate;
an anode layer, disposed on the planarization layer, wherein the anode layer comprises a first anode and a second anode; there is a gap between the first anode and the second anode; the first anode comprises a first reflection portion, and the second anode comprises a second reflection portion; and a reflectivity of the first reflection portion is less than a reflectivity of the second reflection portion; and
a light-emitting layer, disposed on the anode layer, wherein the light-emitting layer comprises a green light emitting portion and a blue light emitting portion; and the green light emitting portion is disposed on the first anode, and the blue light emitting portion is disposed on the second anode,
wherein the first anode further comprises an additional conductive portion, the additional conductive portion being located on the first reflection portion, and the second anode further comprises a first conductive portion and a second conductive portion, the first conductive portion and the second conductive portion being sequentially stacked on the second reflection portion.
