  • Patent number: 9343710
    Abstract: A method of manufacturing an EL display device having a panel part is such that a constituent element of the panel part is formed through film formation in a vacuum atmosphere. After the constituent element of the panel part has been formed on a substrate in the vacuum atmosphere, the post-film-formation substrate is placed on standby during transporting the substrate from a place in the vacuum atmosphere to a place in an atmospheric-pressure atmosphere. The placing the substrate on standby includes a first intake period and a second intake period. During the first intake period, an intake gas is gradually introduced to change the atmosphere, from the first vacuum atmosphere to the second vacuum atmosphere that exhibits a lower degree of vacuum than that of the first vacuum atmosphere. During the second intake period, the intake gas is introduced to change the atmosphere, from the second vacuum atmosphere to the atmospheric-pressure atmosphere.

After the constituent element of the panel part has been formed on a substrate in the vacuum atmosphere, the post-film-formation substrate is placed on standby during transporting the substrate from a place in the vacuum atmosphere to a place in an atomospheric-pressure atmosphere. The placing the substrate on standby includes a first intake period and a second intake period. During the first intake period, an intake gas is gradually introduced to change the atmosphere, from the first vacuum atmosphere to the second vacuum atmosphere that exhibits a lower degree of vacuum than that of the first vacuum atmosphere.
