To provide a semiconductor device including an RFID which can transmit and receive individual information without checking of the remaining charge of a battery or a replacing operation of the battery in accordance with deterioration over time of the battery for driving, and can maintain an excellent state for transmission and reception of individual information even when power of a radio wave or an electromagnetic wave from outside is insufficient. A battery (also described as a secondary battery) is provided as a power supply for supplying power to the RFID. Then, when power which is obtained from a signal received from outside is larger than predetermined power, its surplus power is stored in the battery; and when the power which is obtained from the signal received from outside is smaller than the predetermined power, power which is obtained from the battery is used for the power for driving.

In an active matrix liquid crystal display device, the driver of a gate signal line is provided with a low-supply-voltage drive section and a high-supply-voltage drive section. A level shifter circuit in the high-supply-voltage drive section is made up of two CMOS circuits, to which a supply voltage Vdd2 (high-voltage power supply) is applied. Also, to two n-channel TFWs Tr3 and Tr7 in the level shifter circuit is applied a bias voltage Vdd1 (low-voltage power supply) which is a supply voltage different from the above supply voltage. This structure can prevent a high load from being exerted on only one n-channel TFT, thereby being capable of making the withstand voltage high.

An object is to provide a moving object structure capable of reducing power loss caused when power is supplied from a power feeding device to a moving object by wireless communication. Another object is to provide a moving object structure capable of reducing the strength of a radio wave radiated to the surroundings. Before power is supplied to a moving object, a radio wave for alignment of antennas is output from a power feeding device. That is, radio waves are output from a power feeding device in two stages. In a first stage, a radio wave is output to align positions of antennas of the power feeding device and the moving object. In a second stage, a radio wave is output to supply power from the power feeding device to the moving object.

To provide for a movable electronic device a power receiving device that when charging a battery, simplifies charging of the battery from a power feeder, which is a power supply means, and does not have faults due to an external factor relating to a relay terminal, or damage of the relay terminal, that are caused by directly connecting the battery and the power feeder, and further, to provide an electronic device including the power receiving device. An antenna circuit and a booster antenna for supplying electric power are provided in a movable electronic device. The antenna circuit receives a radio signal such as an electromagnetic wave via the booster antenna, and electric power that is obtained through the receiving of the radio signal is supplied to the battery through a signal processing circuit.
