Abstract: Reliability of a flexible electronic device is improved. Damage due to curving in a flexible electronic device is prevented. The present inventor has reached an idea of setting an allowable value of a radius of curvature at the time of curving a flexible electronic device. The electronic device includes a sensing portion which determines a three-dimensional shape of the curved region. When a curving with a radius of curvature smaller than the allowable radius of curvature is detected, an alert is sent to a user.
