Claim 16:
17. A manufacturing method of an array substrate, comprising steps of:
providing a substrate;
forming a thin-film transistor layer on the substrate;
providing a mixed solution comprising an insulating nanoparticle, organic polymer, and a solvent in a volume ratio of (0.9-1.1):(0.9-1.1):(0.7-1.2);
coating the mixed solution on the substrate and the thin-film transistor layer to form an uncured mixed film layer; and
performing an annealing heat treatment on the uncured mixed film layer to form a cured insulating nanoparticle layer and a cured organic polymer layer, wherein the insulating nanoparticle layer is disposed on the substrate and covers the thin-film transistor layer, and the organic polymer layer is stacked on a side of the insulating nanoparticle layer away from the thin-film transistor layer and covers the insulating nanoparticle layer.
