Display device and curvature variation device adapted thereto

摘要

A display device includes a flexible display substrate and a curvature variation device. The curvature variation device is disposed on a rear surface of the flexible display substrate. A length of the curvature variation device is varied in response to an operation of a user to the curvature variation device, to vary a curvature of the flexible display substrate.
