Patent ID: 8018143

Claim:
A method of manufacturing an organic electroluminescent display device, comprising: forming a first electrode on a first substrate including a plurality of pixel regions; forming a patterned spacer on the first electrode in the pixel region; forming an organic light emitting layer on the first electrode in the pixel region and on the patterned spacer; forming a second electrode on the organic light emitting layer; forming a calcium layer on the second electrode, and covered by the second electrode; forming a calcium oxide layer on the second electrode by exposing the calcium layer to oxygen gas, wherein a calcium oxide of the calcium oxide layer diffuses into a portion of the second electrode such that the portion of the second electrode has an insulating property; forming a moisture-absorbing layer on the calcium oxide layer; forming a driving thin film transistor on a second substrate; and forming a connection electrode connected to the driving thin film transistor, the connection electrode contacting the second electrode on the patterned spacer.
