ARRAY SUBSTRATE, DISPLAY DEVICE AND MANUFACTURING METHOD

摘要

An array substrate, display device and manufacturing method; the array substrate comprising a thin film transistor and a pixel electrode (9); an active layer (4) of the thin film transistor is formed by a first region (401) of an oxide semiconductor layer (4); the oxide semiconductor layer further comprises a second region (402); the pixel electrode (9) overlaps with the second region (402) of the oxide semiconductor layer (4) to form a storage capacitance; the second region (402) of the oxide semiconductor layer (4) constitutes a first electrode plate (402) of the storage capacitance; the pixel electrode (9) corresponding to the second region (402) of the oxide semiconductor layer (4) constitutes a second electrode plate (9); and dielectric layers (7, 8) are disposed between the first electrode plate (402) and the second electrode plate (9).
