Laminate having organic mask and method for manufacturing organic electroluminescent device using same
Provided are a laminate including an organic material mask and a method for preparing an organic light emitting device using the same. The laminate includes a substrate; and a mask provided on the substrate and including an organic material.
1. A method for preparing an organic light emitting device, comprising:
preparing a substrate;
patterning a mask including an organic material on the substrate;
depositing one or more of a first electrode, an organic material layer, and a second electrode on the substrate and the mask; and
removing the mask,
wherein the mask has a pattern shape and the mask has a shape of reversely tapered angle.
2. The method of claim 1 , wherein the substrate is glass, an inorganic material substrate, a plastic substrate, or a flexible substrate.
3. The method of claim 1 , wherein the organic material includes one or more selected from a group consisting of polyimide, polyethylene, and polyvinylchloride.
4. The method of claim 1 , wherein the mask including the organic material is formed on the substrate by a printing method.
5. The method of claim 1 , wherein further comprising:
forming an auxiliary electrode on the first electrode,
wherein the auxiliary electrode includes at least one of Cr, Mo, Al, Cu, and an alloy thereof.
6. The method of claim 5 , wherein further comprising:
forming an insulating layer on the auxiliary electrode,
wherein the insulating layer includes at least one of a general photoresist material, polyimide, polyacryl, silicon nitride, silicon oxide, aluminum oxide, aluminum nitride, alkaline metal oxide, alkaline earth metal oxide.
7. The method of claim 6 , wherein a thickness of the insulating layer is one of 10 nm to 10 μm.
8. The method of claim 1 , wherein the shape of reversely tapered angle is prepared by two or more printing processes.
