Claim Text:
1. A method of manufacturing an EL display device having a panel part, the panel part comprising: a light emitting part in which a plurality of pixels are arrayed; and a thin-film transistor array device to control light emission of the light emitting part, the method comprising the steps of: forming a constituent element of the panel part on a substrate, through film formation in a vacuum atmosphere; and placing the post-film-formation substrate on standby in a load lock chamber, after the step of forming the constituent element, during transporting the post-film-formation substrate from a place in the vacuum atmosphere to a place in an atmospheric-pressure atmosphere, wherein the step of placing the post-film-formation substrate on standby includes a first intake period and a second intake period, the first intake period being longer in time than the second intake period, the first intake period being for gradually introducing an intake gas to change a first vacuum atmosphere into a second vacuum atmosphere lower in degree of vacuum than the first vacuum atmosphere, the second intake period being for introducing the intake gas to change the second vacuum atmosphere into the atmospheric-pressure atmosphere; and a rate of change of pressure in the load lock chamber during the first intake period is less than the rate of change of pressure in the load lock chamber during the second intake period.
