Abstract
The present disclosure provides a manufacturing method for an array substrate and a liquid crystal display device. The manufacturing method for an array substrate may include: providing a substrate; forming a thin film transistor device comprising a source and a drain on the substrate; covering a passivation layer, a blocking layer, and a photoresist layer on the thin film transistor device, sequentially; processing the photoresist layer to divide the blocking layer and the passivation layer into a first region and a second region corresponding to positions of an active area, and a third region corresponding to a position of the thin film transistor device. By the above-mentioned manufacturing method, on one hand, a number of mask processes may be reduced, and the manufacturing efficiency may be improved. On the other hand, peeling efficiency of the photoresist may be improved.
