Abstract
To provide a circuit board in which a curvature of a display surface can be controlled, or to provide a highly portable circuit board. A circuit board includes a substrate with flexibility and a curvature control mechanism. The curvature control mechanism includes a first electromagnet and a second electromagnet provided over a first surface of the substrate, an insulating film provided over the first and second electromagnets, and wirings electrically connected to the first and second electromagnets.
