An array substrate, a display panel and a display device are provided. The array substrate includes a base substrate (101), and a plurality of gate lines (102), a plurality of data lines (106) and a plurality of subpixels (01) disposed on the base substrate (101). A first electrode (107) and a second electrode (108) insulated from each other are disposed in each of the subpixels (01); the first electrode (107) includes a plurality of first electrode strips (1070); the second electrode (108) includes a plurality of second electrode strips (1080). In projections of the plurality of first electrode strips (1070) and the plurality of second electrode strips (1080) on the base substrate (101), a distance along a direction parallel to a first direction between a projection of one second electrode strip (1080) and a projection of a first electrode strip (1070) adjacent to the second electrode strip (1080) in the first direction is S1; a distance along the direction parallel to the first direction between the projection of the second electrode strip (1080) and a projection of one first electrode strip (1070) adjacent to the second electrode strip (1080) in a direction opposite to the first direction is S2; the plurality of subpixels (01) include a first domain (1101) and a second domain (1102); the first domain (1101) includes a part in which S1 is greater than S2; and the second domain (1102) includes a part in which S1 is less than S2. The array substrate has higher tolerance in process bias such as CD bias and overlay margin.
