Abstract: Provided in an embodiment of the present disclosure are an array substrate, a method for preparing the same, and a display device. The method for preparing the array substrate includes: providing a base substrate and forming a film including an organic material and responsive particles on the base substrate; and applying at least one of an electric field and a magnetic field to the film. The responsive particles drive the organic material to flow under the at least one of the electric field and the magnetic field, thereby planarizing the film to form an organic layer. By adding particles in the organic material that respond to at least one of an electric field and a magnetic field, responsive particles move under the action of the applied electric field and/or magnetic field, and the organic material is driven to be moved along with the movement of the responsive particles.
