Abstract: A-light-emitting device which realizes a high aperture ratio and in which the quality of image is little affected by the variation in the characteristics of TFTs. The channel length of the driving TFTs is selected to be very larger than the channel width of the driving TFTs to improve current characteristics in the saturated region, and a high VGS is applied to the driving TFTs to obtain a desired drain current. Therefore, the drain currents of the driving TFTs are little affected by the variation in the threshold voltage. In laying out the pixels, further, wiring is arranged under the partitioning wall and the driving This are arranged under the wiring in order to avoid a decrease in the aperture ratio despite of an increase in the size of the driving TFT.

Abstract: 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 insulting film, and the organic resin film is partially exposed to light to be opened. Thereafter, an inorganic insulting 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.

Abstract: Disclosed is a display device and an electronic apparatus incorporating the display device. The display device includes a transistor and a planarization film over the transistor. The planarization film has an opening where an edge portion is rounded. The display device further includes a first electrode over the planarization film and an organic resin film over the first electrode. The organic resin film also has an opening where an edge portion is rounded. The organic resin film is located in the opening of the planarization film. The first electrode and the transistor are electrically connected to each other through a conductive film. The first electrode is in contact with a top surface of the conductive film. Over the first electrode, a light-emitting member and a second electrode are provided.
