Patent attributes
A method of manufacturing an organic electroluminescent display device may comprise forming transistors on a substrate, forming a lower electrode over an insulating layer, forming an insulating layer on the transistors, the lower electrode being coupled to a source or a drain of each of the transistors, forming a bank layer on the lower electrode, the bank layer having openings to expose part of the lower electrode, forming a bus electrode on the bank layer, forming an organic light-emitting layer to cover the lower electrode, the bank layer, and the bus electrode, patterning the organic light-emitting layer using a laser, thereby exposing the bus electrode placed on the bank layer, and forming an upper electrode on the organic light-emitting layer so that the upper electrode comes into contact with the exposed bus electrode.
