Claim 15:
16. The fabrication method of the OLED display panel according to claim 8, wherein the step of sequentially fabricating the gate insulating layer, the gate layer, and the interlayer insulating layer on the side of the active layer away from the buffer layer, wherein the gate layer is patterned to form the gate of the thin film transistor comprises:
patterning the gate layer to form the gate after blanketly depositing the gate insulating layer and the gate layer;
etching the gate insulating layer by using the gate as a self-alignment;
performing a blanket plasma treatment on pre-process film layers formed by the gate layer, the gate, and the metal oxide semiconductor layer; and
forming the entire interlayer insulating layer on the side of the gate away from the gate insulating layer.
