Semiconductor display device


It is an object of the present invention to provide a semiconductor display device having an interlayer insulating film which can obtain planarity of a surface while controlling film formation time, can control treatment time of heating treatment with an object of removing moisture, and can prevent moisture in the interlayer insulating film from being discharged to a film or an electrode adjacent to the interlayer insulating film. An inorganic insulating film containing nitrogen, which is less likely to transmit moisture compared with an organic resin, is formed so as to cover a tft.
