Array substrate and manufacturing method thereof, display device

A method of manufacturing an array substrate, comprising:

• forming at least one array structure on a transparent substrate, wherein the array structure comprises a first pixel unit, a second pixel unit and a third pixel unit arranged row-by-row;
• each of the first pixel unit and the third pixel unit has a single-domain inclining direction, and the second pixel unit has a plurality of domain inclining directions;
• the single-domain inclining direction of the first pixel unit is different from that of the third pixel unit;
• the domain inclining direction of the second pixel unit, at a side adjacent to the first pixel unit, is the same as the single-domain inclining direction of the third pixel unit, and the domain inclining direction of the second pixel unit, at a side adjacent to the third pixel unit, is the same as the single-domain inclining direction of the first pixel unit;
• and
• forming a comb-like first electrode and a plane-like second electrode in each of the first to third pixel units, wherein the first electrode is inclinedly aligned for driving liquid crystal molecules to align according to a corresponding domain inclining direction.
