Display panel and method of manufacturing same

A method of manufacturing a display panel, comprising steps of:

• S10, forming a buffer layer on a substrate;
• S20, forming a patterned active layer on the buffer layer by using indium gallium zinc oxide, the active layer comprising an active island and a first plate independent of the active island;
• S30, sequentially forming a gate insulating layer and a gate metal layer on the active island;
• S40, conducting a portion of the active island exposing the gate insulating layer to form a conductor layer, simultaneously conducting the first plate, forming a protective layer covering the conductor layer, and forming a dielectric layer covering the first plate;
• S50, forming an interlayer dielectric layer covering the active layer and the gate metal layer;
• S60, forming a second metal layer on the interlayer dielectric layer, and patterning the second metal layer to form a source/drain metal layer in contact with the conductor layer;
• S70, forming a passivation layer and a planarization layer on the interlayer dielectric layer;
• S80, forming an anode metal layer in contact with the source/drain metal layer on the planarization layer by using indium tin oxide, and simultaneously forming a second plate on the dielectric layer to form a storage capacitor with the first plate;
• and
• S90, forming a light emitting layer and a cathode metal layer on the anode metal layer.
