Abstract
The invention provides an organic electroluminescent device and a method of manufacturing the same which conveniently reduce or suppress the transfer of ionic impurities into a light-emitting layer, and reduce or prevent the light-emitting property in the light-emitting layer from degrading, which promotes life extension. An organic electroluminescent device includes a functional layer having at least a light-emitting layer between a first electrode and a second electrode. At least a part of the functional layer is formed of the inorganic ion exchange material added to the functional material to form the functional layer.
Claims4
A method of manufacturing an organic electroluminescent device that includes a functional layer having a light-emitting layer and a carrier injection/transport layer between a first electrode and a second electrode, the method comprising:
- adding an inorganic ion exchange material to a functional material;
- and
- forming at least a part of the functional layer using the obtained functional material.
A method of manufacturing an organic electroluminescent device that includes a functional layer having at least a light-emitting layer between a first electrode and a second electrode, the method comprising:
- disposing an inorganic ion exchange material between the first electrode and the second electrode to form an inorganic ion exchange layer.
