Organic electroluminescent element, method for manufacturing organic electroluminescent element, and coating liquid for electron injection and transport layer

摘要

A main object of the present invention is to provide an organic EL element including an electron injection and transport layer containing an organic boron compound, which has excellent characteristics such as efficiency and service life. The present invention achieves the object mentioned above by providing an organic EL element including: an anode; a light emitting layer formed on the anode; an electron injection and transport layer that is formed on the light emitting layer, contains an organic boron compound, and has a crystalline structure; and a cathode formed on the electron injection and transport layer.
