ABSTRACT:
An objective is to increase the reliability of a light emitting device structured by combining TFTs and organic light emitting elements. A TFT (1201) and an organic light emitting element (1202) are formed on the same substrate (1203) as structuring elements of a light emitting device (1200). A first insulating film (1205) which functions as a blocking layer is formed on the substrate (1203) side of the TFT (1201), and a second insulating film (1206) is formed on the opposite upper layer side as a protective film. In addition, a third insulating film (1207) which functions as a barrier film is formed on the lower layer side of the organic light emitting element (1202). The third insulating film (1207) is formed by an inorganic insulating film such as a silicon nitride film, a silicon oxynitride film, an aluminum nitride film, an aluminum oxide film, or an aluminum oxynitride film. A fourth insulating film (1208) and a partitioning layer (1209) formed on the upper layer side of the organic light emitting element (1202) are formed using similar inorganic insulating films.
