Abstract
A method for manufacturing an organic electroluminescent element including, in the following order, an anode, a light-emitting layer, an electron injection layer, and a cathode, the method including the steps of: (A) forming the anode; (B) forming the light-emitting layer; (C) forming the electron injection layer; and (D) forming the cathode, in which the step (C) includes (i) applying an application liquid containing an ionic polymer to form a thin film, (ii) heating the thin film formed, (iii) storing a partially finished organic electroluminescent element obtained in (ii), and thereafter, (iv) heating the thin film again.
