Abstract
The disclosure relates to an array substrate, a manufacturing method thereof, and a display panel. In one aspect, an organic layer is disposed in a display area to release applied forces generated when the array substrate is frequently bent. In another aspect, without adding additional mask sheets, a portion of the organic material in a recess is removed by using a halftone mask, an organic material in other areas of the display area is completely removed, and an organic material of a photoresist layer in a bending area is retained. Therefore, a surface of the organic layer away from the substrate aligns with a surface of the interlayer insulating layer away from the substrate, so that there is no height difference when a top source/drain layer is disposed.
