[0039] For example, a method for manufacturing an organic light-emitting display device includes: providing a substrate; forming an anode layer on the substrate; forming an organic light-emitting layer on the anode layer; forming a cathode layer on the organic light-emitting layer; For the opening of the film plate, the part of the cathode layer and the part of the organic light-emitting layer corresponding to the opening on the substrate are etched and removed by plasma bombardment; Cover plate: bonding the substrate to the cover plate, sintering the outer glass frit and the inner glass frit to form an outer encapsulation layer and an inner encapsulation layer, so that the substrate and the cover The plates are sealed and connected; the base plate and the cover plate are perforated at positions in the inner encapsulation layer to form an organic light-emitting display device with holes.
[0040] In the above embodiment, compared with traditional laser etching, the plasma bomb...
