Abstract
Disclosed is a method for manufacturing an array substrate, the array substrate and a display device which can reduce manufacturing steps of a color filter process and further reduce manufacturing steps of the display device, thereby saving manufacturing cost and time. The method for manufacturing the array substrate includes: forming a thin film transistor on a base substrate; forming a passivation layer having a via hole on a front side of the thin film transistor and forming a photo spacer on a front side of the passivation layer through a halftone mask patterning process. With this method for manufacturing the array substrate, there is no need to prepare the photo spacer on a back side of the color filter substrate. Therefore, it is possible to reduce manufacturing steps of a color filter process, which in turn further reduces manufacturing steps of the display device, thereby saving manufacturing cost and time.
