Abstract

It is an object of the present invention to provide a light-emitting device where periphery deterioration can be prevented from occurring even when an organic insulating film is used as an insulating film for the light-emitting device. In addition, it is an object of the present invention to provide a light-emitting device where reliability for a long period of time can be improved. A structure of an inorganic film, an organic film, and an inorganic film is not continuously provided from under a sealing material under a cathode for a light-emitting element. In addition, penetration of water is suppressed by defining the shape of the inorganic film that is formed over the organic film even when a structure of an inorganic film, an organic film, and an inorganic film is continuously provided under a cathode for a light-emitting element.
