Production method for organic electroluminescent element
Abstract:
The present invention aims at providing a method for producing an organic electroluminescent element, by which a non-light-emitting region can be formed without any accompanying discoloration of a resin substrate. The method for producing an organic electroluminescent element includes a stacking step, in which a first electrode, an organic functional layer and a second electrode are formed by stacking on a resin substrate, and a light irradiation step, in which a prescribed region of the organic functional layer is irradiated with light being free from wavelength components at 340 nm or less.
