Abstract:
1. An imaging apparatus comprising: an insulation substrate; and a plurality of pixels disposed on the insulation substrate, wherein each of the plurality of pixels includes a plurality of thin-film transistors, a conversion element disposed above the plurality of thin-film transistors, and a plurality of insulating layers disposed between the conversion element and the plurality of thin-film transistors, wherein the plurality of thin-film transistors comprises a reading thin-film transistor having a gate electrode electrically connected to the conversion element and a first selecting thin-film transistor electrically connected to a source electrode or a drain electrode of the reading thin-film transistor, and wherein at least one of a signal wiring, to which a signal corresponding to an electric charge obtained by conversion of incident light or radiation performed by the conversion element is transferred, and a gate wiring that supplies a driving signal to a gate electrode of the first selecting thin-film transistor, is disposed between the plurality of insulating layers, wherein each of the pixels further includes a second selecting thin-film transistor electrically connected to the gate wiring, and wherein each of the source electrode and the drain electrode of the reading thin-film transistor is electrically connected to either one of the first selecting thin-film transistor and the second selecting thin-film transistor.
