When the off-state current of a thin film transistor including an oxide semiconductor layer is set to 1×10−13 A or less and the thin film transistor is used as a reset transistor and a transfer transistor of the solid-state image sensor, the potential of the signal charge storage portion is kept constant, so that a dynamic range can be improved.
