Abstract:
1. An image-pickup device comprising: a plurality of pixels, each comprising a photoelectric conversion element that converts light into electric charge, a storage capacitor that stores the electric charge which the photoelectric conversion element has obtained by conversion, reset means for discharging the electric charge in the storage capacitor, and an amplifying thin-film transistor that receives, amplifies, and outputs the electric charge stored in the storage capacitor, and characterized in that a source electrode of the amplifying thin-film transistor is connected to a power-source supplying line, a gate electrode of the amplifying thin-film transistor is connected to the storage capacitor, and the amplifying thin-film transistor forms a source follower circuit, and further wherein one signal line provides both a row reset signal and a row selection signal for each of a plurality of adjacent rows and further wherein the plurality of pixels are arranged such that a group of a plurality of conductive lines are formed between adjacent pixels and contact detecting elements such that at least one conductive line of each group of lines is connected to a pixel and a plurality of the conductive lines are connected to each contact detecting element.
