    Abstract: A semiconductor device having a novel structure is provided in which a transistor including an oxide semiconductor and a transistor including a semiconductor material which is not an oxide semiconductor are stacked. Further, a semiconductor device in which a semiconductor element and a capacitor are formed efficiently is provided. In a semiconductor device, a first semiconductor element layer including a transistor formed using a semiconductor material which is not an oxide semiconductor, such as silicon, and a second semiconductor element layer including a transistor formed using an oxide semiconductor are stacked. A capacitor is formed using a wiring layer, or a conductive film or an insulating film which is in the same layer as a conductive film or an insulating film of the second semiconductor element layer.

    Abstract: A constitution of the display device of the invention is shown in the following. The display device includes a pixel unit including TFTs of which the active layer contains an organic semiconductor material for forming channel portions in the opening portions in an insulating layer arranged to meet the gate electrodes. The pixel unit further includes a contrast media formed on the electrodes connected to the TFTs for changing the reflectivity upon the application of an electric field, or microcapsules containing electrically charged particles that change the reflectivity upon the application of an electric field. The pixel unit is sandwiched by plastic substrates, and barrier layers including an inorganic insulating material are provided between the plastic substrates and the pixel unit. The purpose of the present invention is to supply display devices which are excellent in productivity, light in weight and flexible.

    Abstract: Although an organic resin substrate is highly effective at reducing the weight and improving the shock resistance of a display device, it is required to improve the moisture resistance of the organic resin substrate for the sake of maintaining the reliability of an EL element. Hard carbon films are formed to cover a surface of the organic resin substrate and outer surfaces of a sealing member. Typically, DLC (Diamond Like Carbon) films are used as the carbon films. The DLC films have a construction where carbon atoms are bonded into an SP3 bond in terms of a short-distance order, although the films have an amorphous construction from a macroscopic viewpoint. The DLC films contain 95 to 70 atomic % carbon and 5 to 30 atomic % hydrogen, so that the DLC films are very hard and minute and have a superior gas barrier property and insulation performance.
