摘要：
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. Next, an organic resin film containing photosensitive acrylic resin is applied to the organic insulating film, and the organic resin film is partially exposed to light to be opened. Thereafter, an inorganic insulating film containing nitrogen, which is less likely to transmit moisture compared with an organic resin, is formed so as to cover the opened organic resin film. Then, in the opening part of the organic resin film, a gate insulating film and the two layer inorganic insulating film containing nitrogen are opened partially by etching to expose an active layer of the TFT.
