Abstract
Provided are an array substrate and a manufacturing method thereof, and a display device. The array substrate includes a pixel defining layer including first sub-pixel opening columns and second sub-pixel opening columns that are alternately arranged; the first sub-pixel opening column includes at least two types of sub-pixel openings having different illumination colors; an area of the sub-pixel opening in the second sub-pixel opening column is greater than that of the sub-pixel opening in the first sub-pixel column; in the first sub-pixel opening column, the pixel defining layer between adjacent sub-pixel openings having the same illumination color is made of a lyophilic material, and the pixel defining layer between adjacent sub-pixel openings having different illumination colors is made of a material that is switched between a lyophilic property and a lyophobic property as an external condition changes.
