Manufacturing method for organic light emitting diode display and organic light emitting diode display using the same
A method for manufacturing an organic light emitting diode display includes forming a thin-film transistor on a substrate, forming a protection layer by using a deposition method on an entire surface of the substrate, and forming an organic light emitting element on the protection layer. Forming the protection layer includes forming a first protection layer, a surface thereof including a first wrinkle, and forming a second protection layer on the first protection layer, a surface thereof including a second wrinkle. A first modulus value of the first protection layer is less than a second modulus value of the second protection layer by at least 300 MPa.
