Claim:
1. A method for repairing an organic light-emitting diode (OLED) display device, the OLED display device comprising a lamination structure for forming an OLED, the repair method comprising: determining a position of a foreign particle in the lamination structure; removing the foreign particle and layers over the foreign particle and in a recess region to be formed, so as to form a recess in the lamination structure, in which an opening of the recess is towards external environment; and forming a repair structure in the recess, in which a refractive index of the repair structure is less than that of the lamination structure, and a surface of the repair structure is lower than a surface of the lamination structure; forming a planarization layer on the repair structure, in which a surface of the planarization layer is level with the surface of the lamination structure, wherein a refractive index of the planarization layer is greater than that of the repair structure.
