Abstract:
An array substrate and a manufacturing method thereof are provided. The manufacturing method comprises: depositing a passivation material layer on a TFT layer, wherein the passivation material layer includes a first film layer and a second film layer made of different materials alternatively arranged; using a photoresist layer as a mask to etch the passivation material layer until the first film layer is exposed so as to form a patterned structure; depositing an ITO film on the photoresist layer and the exposed first film layer; and stripping the photoresist layer to form the array substrate. By using different materials with different etching speed, a greater gap between the boundary of the spacer and the boundary of the photoresist structure would be formed to facilitate the photoresist stripping process. Thereby, the stripping efficiency and the stripping uniformity can be enhanced to reduce the probability of photoresist residue.

Claim (Index 1):
A manufacturing method of an array substrate, comprising the steps of:\n depositing a passivation material layer on a thin film transistor (TFT) layer, wherein the passivation material layer includes a first film layer and a second film layer alternatively disposed on the TFT layer, the second film layer is a top layer of the passivation material layer, and the first film layer and the second film layer are made of different materials; using a photoresist layer as a mask to etch the passivation material layer until the first film layer is exposed so as to form a patterned structure corresponding to the photoresist layer, wherein the patterned structure includes a plurality of spacers spaced apart from each other, the spacers are corresponding to the photoresist structures one by one, and a height of the pixel electrode along a direction perpendicular to the substrate is smaller than a height of the spacer along the direction perpendicular to the substrate; depositing an indium-tin oxide (ITO) film on the photoresist layer and the exposed first film layer; and stripping the photoresist layer to form the array substrate.
