<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an organic electroluminescent element having favorable emission lifetime, by which interface mixing can be prevented without being limited to a compound to be used. <P>SOLUTION: In a method for manufacturing an organic electroluminescent element including a plurality of organic functional layers sequentially laminated on a base material, at least one layer of a second and subsequent organic functional layers laminated on a base material is formed by a coating step. In the coating step, when temperature of a coating liquid of the organic functional layers formed through the coating step is denoted as A, and temperature of a surface of the organic functional layer which is a just-under layer of the organic functional layers formed through the coating step is denoted as B, a relationship between A and B satisfies A>B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
