Fabricating method for organic electro luminescence display device having a rib barrier of reverse taper shape and organic electro luminescence display device
This invention relates to a fabricating method of an organic electro luminescence display device that is adaptive for simplifying a process by forming a barrier rib by use of a new material, and an organic electro luminescence display device using the same.A fabricating method of an organic electro luminescence display device according to an embodiment of the present invention includes: 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 that divides an area where the organic light emitting layer is to be formed on the upper substrate by patterning the ZnO film; forming an organic light emitting layer in the cell area that is divided by the barrier rib; and forming a cathode electrode on the organic light emitting layer.
