The present invention provides an IC card that can realize high function without increasing the size of an IC chip, and that can realize cost reduction. The IC card comprises a first single crystal integrated circuit, a second integrated circuit, and a display device. The second integrated circuit and the display device are each formed from a thin film semiconductor film, over a plastic substrate, and the first single crystal integrated circuit is mounted on the plastic substrate so as to be electrically connected to the second integrated circuit. |
