Abstract
Disclosed is a method for manufacturing cathode electrodes of electroluminescent display device capable of forming cathode electrodes of fine patterns. The disclosed comprises the steps of: forming an anode electrode on a transparent insulating substrate; forming an insulating partition having a stripe structure to cross with the anode electrode and define a pixel formation area on the substrate; forming an organic film pixel separated with a predetermined distance, with the insulating partition interposed; depositing a cathode metal layer on the surface of the resulting structure; and forming a cathode electrode exposing a predetermined part of the insulating partition by performing etching processes on the cathode metal layer using laser.
