The present invention is to use a film containing fluoroplastics that is
capable of forming into a lamination as a protective film for protecting
a light-emitting device against moisture or gas such as oxygen so as to
prevent of deterioration of the light-emitting device easier and improve
reliability of the light-emitting device greater than the conventional
light-emitting apparatus. In the present invention, another film can be
stacked on the film containing fluoroplastics by forming irregularities
by means of the surface preparation on the film containing fluoroplastics
or by controlling the content of fluoroplastics in the film containing
fluoroplastics. In addition, in the case that another film is stacked on
the film containing fluoroplastics by controlling the content of
fluoroplastics, the content of fluoroplastics can be controlled by means
of forming the film containing fluoroplastics by sputtering using
sequentially a plurality of targets that has different contents of
fluoroplastics and metallic oxides.
