Array substrate and display panel

An array substrate, comprising:

• a substrate;
• a driving circuit layer, wherein the driving circuit layer is provided with a plurality of thin film transistor (TFT) units, and each of the TFT units is provided with a drain;
• a planarization layer disposed on the driving circuit layer;
• a reflective layer disposed on the planarization layer, wherein the reflective layer comprises a plurality of reflective units, and each of the reflective units corresponds to one of the TFT units;
• an optical dielectric layer disposed on the reflective layer;
• a black light-shielding layer disposed on the planarization layer, wherein the black light-shielding layer comprises a plurality of black light-shielding units, and the black light-shielding units and the reflective units are alternately disposed with each other;
• a first electrode layer disposed on the optical dielectric layer, wherein the first electrode layer comprises a plurality of anodes, and each of the anodes corresponds to the reflective layer and the drain, and passes through a through hole to connect to the drain;
• and
• a pixel defining layer disposed on the black light-shielding units, wherein the pixel defining layer comprises a plurality of pixel defining units, and two adjacent pixel defining units define a pixel defining notch.
