Patent ID: 8623679

Claim:
A method of manufacturing an organic electroluminescence display unit, comprising the steps of: forming a lower electrode on a substrate for each of a first blue organic electroluminescence device and a second organic electroluminescence device of a color different from blue; forming a first hole injection/transport layer having at least one of hole injection characteristics and hole transport characteristics on the lower electrode for each of the first blue organic electroluminescence device and the second organic electroluminescence device; forming an organic light emitting layer of the color different from blue on the first hole injection/transport layer for the second organic electroluminescence device; forming a second hole injection/transport layer made of a low molecular material on the entire surfaces of the organic light emitting layer of the color different from blue and the first hole injection/transport layer for the first blue organic electroluminescence device; forming a blue organic light emitting layer on the entire surface of the second hole injection/transport layer; and forming, in sequence, an electron injection/transport layer having at least one of electron injection characteristics and electron transport characteristics, and an upper electrode on the entire surface of the blue organic light emitting layer.
