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.
