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.
