Method of repairing bright spot defect of organic light-emitting display
Abstract:
A method of repairing an organic light-emitting display capable of reducing an eliminated area of an electrode or the like, and preventing a decline in display quality is provided. The method of repairing an organic light-emitting display, the organic light-emitting display including an organic light-emitting device, the organic-emitting device including a plurality of pixels, each of the plurality of pixels including a first electrode, an organic layer including a light-emitting layer, and a second electrode on a substrate in order, each of the plurality of pixels emitting light from a light-emitting region where the first electrode and the second electrode overlap each other with the organic layer in between, the method includes a step of: applying a laser beam to the periphery of a light-emitting region of a pixel which is constantly a bright spot.
