Abstract: An object of the present invention is to provide a light emitting device in which variations in an emission spectrum depending on a viewing angle with respect to a side from which luminescence is extracted are decreased. A light emitting device according to the invention has a transistor, an insulating layer covering the transistor and a light emitting element provided in an opening of the insulating layer. The transistor and the light emitting element are electronically connected through a connecting portion. Additionally, the connecting portion is connected to the transistor through a contact hole penetrating the insulating layer. Note that the insulating layer may be a single layer or a multilayer in which a plurality of layers including different substances is laminated.

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.
