Patent ID: 7186439

Claim:
A method of manufacturing an organic electroluminescent display having an organic electroluminescent device, comprising the steps of: forming a luminescent layer and an electron transporting layer to be arranged on the luminescent layer in succession; wherein: the luminescent layer and the electron transporting layer to be arranged on the luminescent layer are formed in vacuum by evaporation, in which time a first moving evaporation source for retaining and evaporating material of the luminescent layer and a second moving evaporation source for retaining and evaporating material of the electron transporting layer are placed below a substrate for the luminescent layer and the electron transporting layer to be formed on, and the first and second moving evaporation sources are relatively moved parallel with a surface of the substrate for the luminescent layer and the electron transporting layer to be formed on while the luminescent layer and the electron transporting layer are formed in succession; the first and second moving evaporation sources are opposed to each other below the substrate so as to be capable of movement from one end of the substrate to the other; the luminescent layer and the electron transporting layer are formed in succession by evaporating the materials retained in the first and second moving evaporation sources while the respective moving evaporation sources are moved by turns; and the first moving evaporation source moves from a first position displaced from the substrate along the direction of movement, and the second moving evaporation source moves from a second position opposite to the first position and displaced from the substrate along the direction of movement; and evaporating the materials retained in the first and the second moving evaporating sources while the respective moving evaporation sources are moved by turns to respectively make at least one reciprocal movement from one of the substrate to the other.
