1. A TFT comprising:

  • a first capacitor formed so as to have a region where a first capacitor electrode connected to a source electrode and a second capacitor electrode are arranged to be stacked in a thickness direction and mutually opposed across a first dielectric layer therebetween;

    a second capacitor formed so as to have a region where a third capacitor electrode and a fourth capacitor electrode are arranged to be stacked in the thickness direction and mutually opposed across a second dielectric layer therebetween;

    a first lead-out line led out from the first capacitor electrode in a planar direction;

    a second lead-out line led out from a gate electrode in a planar direction;

    a third lead-out line out from the third capacitor electrode in a planar direction;

    a fourth lead-out line led out from the fourth capacitor electrode in a planar direction;

    a first interconnection intersecting the second lead-out line and the fourth lead-out line when viewed in the thickness direction; and

    a second interconnection intersecting the first lead-out line and the third lead-out line when viewed in the thickness direction,the second capacitor electrode and the gate electrode being connected to each other via the second lead-out line,the third capacitor electrode and the source electrode not being connected to each other,the fourth capacitor electrode and the gate electrode not being connected to each other.
