Abstract:
1. A two-dimensional sensor array comprising a plurality of optical sensor circuits which are two-dimensionally arranged and each of which includes: at least a photodiode outputting a signal with a value according to a quantity of light received by the photodiode; a thin film transistor element; and a charge storage element, the charge storage element having one electrode thereof electrically connected to a cathode electrode of the photodiode and having the other electrode thereof electrically connected to a driving wiring for supplying a driving signal to the charge storage element, the thin film transistor element having a gate electrode thereof electrically connected to a cathode electrode of the photodiode and having a drain electrode thereof electrically connected to an optical sensor output wiring, and the driving wiring for the charge storage element being electrically connected to a power supply wiring electrically connected to a source electrode of the thin film transistor element.
