Abstract: An array substrate, preparation method thereof, display panel and display device are provided. The array substrate includes a base substrate and a plurality of thin film transistors distributed on the base substrate in an array. Each thin film transistor includes: a light-shielding block formed on the base substrate and provided with a first groove of which an opening direction is away from the base substrate; a buffer layer formed on one side of the light-shielding block away from the base substrate, a region of the buffer layer corresponding to the first groove being disposed with a second groove of which an opening direction is away from the base substrate; and a channel layer formed in the second groove. The structure uses bulges on two sides of the first groove to shield the light rays in regions without the thin film transistor, thereby improving the stability of the thin film transistor.

Abstract: The present disclosure provides a positive photoresist composition including a major adhesive material and a photosensitizer, wherein the photoresist composition further includes a photoisomerizable compound which would be converted into an ionic structure with an increased degree of molecular polarity after ultraviolet irradiation. The formation of the ionic structure with increased polarity of the molecule reduces the adhesion between the positive photoresist and the organic film layer, facilitates stripping after formation of the via, and improves the product rate of pass. Further, the present disclosure provides a via-forming method using the positive resist composition, a display substrate including the via formed by the via-forming method, and a display device including the display substrate.
