A manufacturing system capable of enhancing reliability and luminance of a
light emitting element is provided which uses an EL material of very high
purity in evaporation. The system is also capable of using an EL material
efficiently. Instead of a glass jar, a container (first container 11a) to
be set in an evaporation apparatus is employed and a material maker (18)
stores an EL material (12), or refines it by sublimation and stores,
directly in the container. The container is then transferred to a light
emitting device maker (19) for evaporation. With a manufacturing system
as such, impurities are prevented from contaminating a highly pure EL
material. This system also eliminates the trouble of transferring an EL
material from a glass jar to a container. The container may be recovered
by the material maker and the EL material remaining in the container may
be collected for reuse by the manufacturing system.
