A preparation method for an array substrate, comprising: preparing a pixel driving circuit (2) on a substrate (1); preparing an insulating flat layer (4) on the substrate (1); and preparing a plurality of pixel electrodes (3) on the substrate (1). The plurality of pixel electrodes (3) are respectively connected to the pixel driving circuit (2) by means of via holes (40) arranged in the insulating flat layer (4), the plurality of pixel electrodes (3) are arranged in an array, a spacing distance (b) between any two adjacent pixel electrodes (3) along the row direction and/or the column direction of the array is less than or equal to a set value, a (2n−1)th pixel electrode is a first pixel electrode (31), a (2n)th pixel electrode is a second pixel electrode (32), the preparation of the pixel electrodes (3) comprises: the first pixel electrode (32) is prepared by means of a first patterning process; and the second pixel electrode (32) is prepared by means of a second patterning process, and N is a positive intege
