Method and apparatus for correcting bright spots in an OLED by laser

A method of manufacturing an organic electroluminescence display apparatus, the method comprising:

• preparing the organic electroluminescence display apparatus, the organic electroluminescence display apparatus including:
• a plurality of picture elements in which a lower electrode, an organic layer including an emission layer, and an upper electrode are stacked;
• and
• partition walls each disposed between adjacent ones of the picture elements, each of the partition walls having a forward-tapered shape in a cross section,
• wherein at least one of the picture elements is a bright spot defective element that always lights or blinks;
• and
• applying a laser beam to an area of the upper electrode 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 corresponding to an emitting part of the emission layer, the emitting part being separated by bottom edges of the partition walls,
• wherein the applying of the laser beam includes
• transforming, in the bright spot defective element, the upper electrode and an electron transmission layer by focusing the laser beam on the upper electrode, and
• in the transforming, an area that is transformed in the electron transmission layer in the bright spot defective element is enlarged by application of the laser beam.
