Abstract: In a method for manufacturing an organic EL display device, an underlying film is formed on each of a plurality of crystal oscillators of a film thickness measuring device. A crystal oscillator to be used for thickness measurement of the thin film is selected from the plurality of crystal oscillators with the underlying film formed thereon. The thin film is formed on the selected crystal oscillator and the substrate of the organic EL display device. A thickness of the thin film formed on the substrate of the organic EL display device is measured on the basis of a thickness of the thin film formed on the selected crystal oscillator, while forming the thin film. The crystal oscillator used for thickness measurement of the thin film is changed for another crystal oscillator on the basis of the thickness of the thin film formed on the selected crystal oscillator.
