Abstract

A method includes: (a) preparing the organic electroluminescence display apparatus including: plural elements in which a reflective anode, an organic layer including an emission layer, and a transparent cathode are stacked; and partition walls, in which at least one of the picture elements is a bright spot defective element that always lights or blinks and (b) applying a laser beam to an area of the transparent cathode in the bright spot defective element, to draw a closed line and to have an unirradiated area along a periphery of the area, the area reflecting an emitting part. Step (b) includes (b-1) transforming the transparent cathode and an electron transmission layer by focusing the laser beam on the transparent cathode. In step (b-1), an area transformed in the electron transmission layer is enlarged by application of the laser beam.
