In this embodiment, an interval distance between a deposition source holder 17 and an object on which deposition is performed (substrate 13) is reduced to 30 cm or less, preferably 20 cm or less, more preferably 5 to 15 cm, and a deposition source holder 17 is moved in an X direction or a Y directio
In this embodiment, an interval distance between a deposition source holder 17 and an object on which deposition is performed (substrate 13) is reduced to 30 cm or less, preferably 20 cm or less, more preferably 5 to 15 cm, and a deposition source holder 17 is moved in an X direction or a Y direction in accordance with an insulator (also called a bank or a barrier) in deposition, and a shutter 15 is opened or closed to form a film. The present invention can cope with an increase in size of a deposition apparatus with a further increase in size of a substrate in the future.
