1. A display panel, comprising:
a substrate layer;
an anode layer disposed on the substrate layer and comprising a plurality of anodes;
a pixel separating layer disposed on the substrate layer, wherein the pixel separating layer comprises a plurality of pixel opening regions and a non-opening region disposed between two adjacent pixel opening regions, and one of the pixel opening regions corresponds to one of the anodes;
an organic light-emitting layer disposed on the anode layer and the pixel separating layer, and
a cathode layer disposed on the organic light-emitting layer,
wherein the cathode layer comprises at least one via hole corresponding to the non-opening region of the pixel separating layer; and
the display panel further comprises a barrier layer, wherein the barrier layer covers the cathode layer and fills the via hole.
