    摘要: The present invention provides an array substrate, a preparation method thereof and a display device. The array substrate includes at least one thin film transistor and a resin layer having at least one resin via hole, wherein a film-thickness-difference-adjusting layer used for reducing the film thickness difference at the resin via hole is arranged at the lower part of the resin layer in at least a part of the resin via hole. By providing the film-thickness-difference-adjusting layer, the film thickness difference at the resin via hole can be effectively reduced, and when a photolithographic process is performed, the difference of the thickness of the photoresist here and the thicknesses at other positions is reduced, so that the via hole fluctuation of a passivation layer caused by the larger film thickness difference at the resin via hole is improved, and the metal residue problem of the pixel electrodes is effectively avoided.
