Patent ID: 6921627

Claim:
A method for manufacturing an organic electroluminescent device, comprising the steps of: forming a conductive layer on an insulating substrate; forming a photoresist pattern layer having a plurality of striped elements a first direction on said conductive layer; etching said conductive layer by a dry etching process using a first plasma gas and using said photoresist pattern layer as an etching mask in a chamber to form striped lower electrodes; depositing an insulating layer on said photoresist pattern layer and on said insulating substrate between said lower electrodes by a plasma deposition process using a second plasma gas in said chamber; performing a lift-off operation upon said photoresist pattern layer to remove said photoresist pattern layer and a part of said insulating layer on said photoresist pattern layer; forming at least one organic thin film layer including an emitting layer on said insulating layer and said lower electrodes; and forming a plurality of striped upper electrodes on said organic thin film layer along a second direction different from said first direction.
