The curvature remotely adjustable curved-surface display device of the present invention has a remotely controllable motor, an active rod, and a slave rod deployed therein. The active rod has a gear and the first slave rod has a rack bar. When receiving a remote control signal transmitted from a remote terminal, the remotely controllable motor can actuate the gear on the active rod to rotate such that the active rod and the first slave rod move close to each other or away from each other. Such a process applies forces to the display panel, thereby carrying out remotely controlling the curvature of the display panel.
