Array substrate and manufacturing method therefor

An array substrate and a manufacturing method therefor. The method comprises: manufacturing a switch array layer on a base substrate (21); forming a colour resistance layer (27) on the switch array layer, wherein the colour resistance layer (27) comprises a red colour film, a green colour film and a blue colour film, and a via hole is formed on the colour resistance layer (27); forming a transparent conductive layer (28) on the colour resistance layer (27); and forming a light-shielding layer (29) on the transparent conductive layer (28).
