Patent ID: 7575494

Claim:
A fabricating method of an organic electro luminescence display device, comprising: forming an anode electrode on an upper substrate; depositing ZnO on the entire surface of the upper substrate and forming a ZnO film by making the deposited ZnO grow crystals; forming a barrier rib with a reverse taper shape by over-etching the ZnO film; depositing an insulation layer on the entire surface of the upper substrate on which the barrier rib is formed and forming a spacer separated from the barrier rib by patterning the insulation layer, wherein the barrier rib and the spacer divide an area of the upper substrate on which an organic light emitting layer is to be formed; forming an organic light emitting layer in the cell area that is divided by the barrier rib and the spacer; and forming a cathode electrode on the organic light emitting layer.
