A method of manufacturing an organic EL display in which organic EL devices are prevented from being promoted in degradation by interfaces that occur between the hole transporting layer and the luminescent layer and between the luminescent layer and the electron transporting layer during the formation of the organic EL devices. The material of the luminescent layer is evaporated from a first evaporation source. At that time, the first evaporation source is moved from one end of a glass substrate to the other. Consequently, the luminescent layer is formed evenly on the glass substrate. After the formation of the luminescent layer is completed, the material of the electron transporting layer is evaporated from a second evaporation source. The second evaporation source is moved as if the first evaporation source is, whereby the electron transporting layer is formed evenly.
A method of manufacturing an organic electroluminescent display having an organic electroluminescent device, comprising the step of forming a luminescent layer and an electron transporting layer to be arranged on the luminescent layer in succession.
A method of manufacturing an organic electroluminescent display having organic electroluminescent devices for emitting luminescence in a plurality of colors, comprising the step of forming a luminescent layer and an electron transporting layer to be arranged on the luminescent layer in an identical formation chamber in succession with respect to each color.
