Abstract
The present invention includes 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 has 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.
