Abstract
To provide an organic EL element in which adhesiveness of layers constituting the organic EL element, such as a functional layer, is enhanced, whereby high reliability due to extension of lifetime or enhancement of quality due to high brightness can be accomplished, and a method of manufacturing the organic EL element. There is provided an organic EL element having a functional layer including at least a light emitting layer between a pair of electrodes. The surface of at least one layer among the functional layer is rough.
Claims9
A method of manufacturing an organic EL device having a functional layer including at least a light emitting layer between a pair of electrodes,
- wherein at least one layer of the functional layer is formed by performing a coating step of applying a base material for the functional layer by using a liquid droplet ejecting method and a drying step of drying the base material applied in the coating step by using a vacuum dry method.
