ABSTRACT:
An image sensor1has a substrate2and primary light-receiving pixels4arrayed in the direction of the surface of the substrate, and the primary light-receiving pixels are formed by laminating plural secondary light-receiving pixels10, 20and30which sense lights in different wavelength ranges, respectively, via at least sealing insulation layers18and28between adjacent secondary light-receiving pixels in the thickness direction. Each secondary light-receiving pixel includes a photoelectric conversion portion14, 24,or34for photoelectrically converting the lights and a signal output portion12, 22or32for outputting signals from a thin film transistor40according to charges generated by the photoelectric conversion portion, and the active layer48of the thin film transistor is formed from an oxide semiconductor or organic semiconductor.
