Abstract:
1. A manufacturing method of a display device provided with a film formed by ejecting a liquid onto a substrate and drying the liquid, the method comprising: evaluating the impact of an evaporation rate of a solvent included in the liquid on a display quality of the display device; storing an elapsed time, as a threshold value, from ejection of the liquid onto the substrate to when the evaporation of the solvent causes display irregularities to the display device; ejecting the liquid onto the substrate; moving the substrate on which the liquid is ejected to a drying device; drying the liquid using the drying device to form the film; and determining whether an elapsed time after ejecting the liquid onto the substrate exceeds the threshold value or not, between the step of ejecting the liquid and the step of moving the substrate, wherein in determining whether the elapsed time after ejecting the liquid onto the substrate exceeds the threshold value or not, if the elapsed time has exceeded the threshold value, a warning is issued by an alarm or the substrate is carried out of a film formation device to prevent the substrate from moving to the drying device.
