Abstract

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.
