Array substrate with responsive particles, reparation method thereof, and display device

A manufacturing method of an array substrate, comprising:

• providing a base substrate;
• forming a thin film transistor on the base substrate, wherein a surface of the thin film transistor close to the film has a concave region;
• forming a film comprising an organic material and responsive particles and covering the surface of the thin film transistor on the base substrate;
• and
• applying at least one of an electric field and a magnetic field to the film, wherein 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 concave region and the film to form an organic layer,
• wherein the forming the film comprising the organic material and the responsive particles comprises:
• forming an organic film by using the organic material, and adding the responsive particles to the organic film, and
• the adding the responsive particles to the organic film comprises doping the responsive particles in the organic film by inkjet printing.
