Abstract
A substrate, manufacturing method thereof, and an organic electroluminescent device using the same are provided, belonging to photoelectron field. The substrate includes a paper layer (102), a first protection layer (101) formed on the lower surface of the paper layer, and a second protection layer (103) formed on the upper surface and covering the same of the paper layer. The substrate, solves problems of paper which is easy to absorb humidity and has high permeability of oxygen by a protection processing that said paper is coated with the heat seal film of polyethylene terephthalate coated with Polyvinyl Dichloride. At the meantime, the substrate has the advantages of cheap material, extensive sources, simple manufacturing process, good flexibility of the substrate, and good capability of preventing the permeability of water as well.
