Title: DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Abstract:
A display substrate and manufacturing method therefor, and a display device, the manufacturing method comprises: forming a substrate (1); forming a thin film transistor on the substrate (1), wherein the thin film transistor comprises a gate electrode (21), a source electrode (22), a drain electrode (23) and an active layer (24); forming a second insulating layer (4) between the gate electrode (21) and the active layer (24); forming a first insulating layer (3) on the substrate (1) and forming the active layer (24) in the first insulating layer (3); forming a third insulating layer (5) on the thin film transistor; forming a pixel electrode (6) on the third insulating layer (5); and forming a fourth insulating layer (7) on the pixel electrode (6), wherein at least one layer of the substrate (1), the first insulating layer (3), the second insulating layer (4), the third insulating layer (5) and the fourth insulating layer (7) is made of organic material and at least one layer of them is made of inorganic material.
