Abstract:
1. A semiconductor device comprising: a switching thin film transistor which operates when a selection signal is applied to a gate and also captures a data signal; an element-driving thin film transistor in which a drain is connected with a drive power source, a source is connected with an element to be driven, and a gate receives a data signal supplied from the switching thin film transistor, for controlling electric power supplied from the drive power source to the element to be driven; a storage capacitor having a first electrode connected with the switching thin film transistor and with the gate of the element-driving thin film transistor and a second electrode connected between the source of the element-driving thin film transistor and the element to be driven, for holding a gate-source voltage of the element-driving thin film transistor in accordance with the data signal; and a switching element for controlling a potential of the second electrode of the storage capacitor.
