Abstract: The present disclosure relates to the technical field of display, and discloses an array substrate, a preparation method therefor, and a display device. When dielectric layers, such as a buffer layer, an interlayer dielectric layer, and a gate insulation layer, are formed between a source-drain electrode and a substrate, the thickness of at least one dielectric layer among said dielectric layers underneath a first through hole for connecting a drain electrode and an anode is increased, which is to say that the drain electrode is raised to be further away from the substrate, causing the drain electrode to be closer to a surface of a planarization layer that faces away from the substrate, i.e., reducing the thickness of a portion of the planarization layer above the drain electrode.

Abstract: Embodiments of the present disclosure provide an array substrate and a manufacturing method thereof, and a display device. The array substrate includes a base substrate, a first electrode pattern, a second electrode pattern, and an active layer pattern disposed on the base substrate, a first electrode protection pattern coating the first electrode pattern, and a second electrode protection pattern coating the second electrode pattern. The active layer pattern is disposed between the first electrode pattern and the second electrode pattern. The first electrode protection pattern and the second electrode protection pattern are connected to two sides of the active layer pattern, respectively. The problem that, the active layer pattern cannot be connected to the first electrode pattern and the second electrode pattern due to the surface oxidation, when the first electrode pattern and the second electrode pattern adopt material with low resistance characteristic, is avoided, thus increasing the product yield.
