A manufacturing method of a display device comprising: forming a first layer of a semiconductor on a glass substrate, forming a second layer of a first metal on the first layer, forming a third layer of a first insulating material on the second layer, forming a fourth layer of a second metal or a metal oxide on the third layer, coating precursor of polyimide on the fourth layer, making a polyimide substrate by baking the precursor of polyimide to make a polyimide substrate, forming pixels on the polyimide substrate, separating the polyimide substrate and the glass substrate by making peel off between the second layer and the third layer with irradiation of a laser beam on the first layer.

A vapor deposition apparatus disclosed in an embodiment is configured to allow an electromagnet (3) to attract a vapor deposition mask, and comprises a control circuit (7) connected between the electromagnet (3) and a power supply circuit (6) for driving the electromagnet (3). The control circuit gradually changes a magnetic field to be generated by the electromagnet (3) when a current is applied to the electromagnet (3). As a result, the change in current to flow in an electromagnetic coil (32) of the electromagnet (3) becomes gradual and an effect of electromagnetic induction is reduced, thereby suppressing the defect of elements formed on a substrate for vapor deposition or the deterioration in property of the element.
