An organic EL display and fabricating method thereof enable a reduction in a process time by simplifying a fabricating process in a manner that a pattern of a single insulating layer is formed so as to have both functions of insulator and separator, increase an aperture ratio, and reduce a product cost. A plurality of stripe type first electrodes are provided on a transparent substrate, an insulating layer pattern is stacked on the transparent substrate and the first electrodes so as to cross with the first electrodes, a half tone pattern of insulator is stacked on the transparent substrate between the insulating layer pattern and between the first electrodes, a plurality of organic light-emitting layers are provided on a plurality of the first electrodes, respectively, and a plurality of second electrodes are provided on a plurality of the organic light-emitting layers

Method of fabricating organic electroluminescent displays having a stacked insulating layer with halftone pattern

Disclosed is a method of fabricating an organic electroluminescent display enabling to improve device characteristics and reliability by performing excimer laser annealing on a passivation layer locally. The present invention includes forming an anode layer, an organic electroluminescent layer, and a cathode layer successively on a transparent substrate, forming a passivation layer on the transparent substrate including the cathode layer, and performing heat treatment on the passivation layer locally.

Method of making organic electroluminescent display

Described is a method of fabricating an organic electroluminescent display (hereinafter abbreviated OELD) enabling to increase a throughput efficiency by carrying out a foregoing OELD process, dividing a large-scaled substrate, and carrying out a following OELD process in order. The present invention includes the steps of forming a first electrode layer on a large-scaled substrate, dividing the large-scaled substrate into a plurality of small substrates, forming an organic electroluminescent layer on the first electrode layer of at least one of the small substrates, and forming a second electrode layer on the organic electroluminescent layer.
