A display device which can elevate and rotate to a position includes a base, a controlling member mounted to the base, and a supporting frame. A display is mounted on the supporting frame, and a first magnetic piece is positioned on the controlling member. A second magnetic piece is positioned on the supporting frame. The first and second magnetic pieces are configured to attract each other. The controlling member includes a first elastic piece between the base and the supporting frame. The first elastic piece retracts to enable the supporting frame to rotate. The controlling member can slide to detach the second magnetic piece from the first magnetic piece, and the first elastic piece retracts to allow an upward rotation of the supporting frame thereby changing height of the display.
