transmit a control signal to the mobile terminal, the control signal indicating the monitor window is oriented in the second display direction.

2. The display device of claim 1, wherein after transmitting the control signal to the mobile terminal, the controller is configured to receive information related to the second display direction from the mobile terminal.

3. The display device of claim 1, wherein the user command is received through a touchscreen.

4. The display device of claim 1, wherein the first screen image and the second screen image share a content image related to a menu or application executed in the mobile terminal.

5. The display device of claim 1, wherein the monitor window has a shape identical to one face of a housing of the mobile terminal.

6. The display device of claim 1, wherein the monitor window is generated at a predetermined position on the second display unit regardless of a display position of at least one object that is previously displayed on the second display unit.

7. The display device of claim 1, wherein the monitor window is generated at a position on the second display unit to avoid blocking at least one object that is previously displayed on the second display unit.

8. The display device of claim 1, wherein when the controller receives a user command for enlarging the second screen image, the controller transmits information to the mobile terminal, the information indicating the user command for enlarging the second screen image is input, and the controller receives a video signal from the mobile terminal corresponding to the information while a size of the monitor window is maintained.

9. The display device of claim 1, wherein when the controller receives a user command for reducing the second screen image, the controller transmits information to the mobile terminal, the control signal indicating the user command for reducing the second screen image is input, and the controller receives a video signal from the mobile terminal corresponding to the information while a size of the monitor window is maintained.

10. The display device of claim 1, wherein when the controller receives a user command for enlarging the monitor window, the controller controls the monitor window to be enlarged and controls the second screen image to be enlarged within the enlarged monitor window while a zoom level of the second screen image is not changed.

11. The display device of claim 1, wherein when the controller receives a user command for enlarging the monitor window, the controller controls the monitor window to be enlarged and transmits information to the mobile terminal, the information indicating the user command for enlarging the monitor window is input, and the controller receives a video signal from the mobile terminal corresponding to the information and controls the second screen image to be enlarged within the enlarged monitor window using the video signal.

12. The display device of claim 1, wherein when the controller receives a user command for reducing the monitor window, the controller controls the monitor window to be reduced and controls the second screen image to be reduced within the reduced monitor window while a zoom level of the second screen image is not changed.

13. The display device of claim 1, wherein when the controller receives a user command for reducing the monitor window, the controller controls the monitor window to be reduced and transmits information to the mobile terminal, the information indicating the user command for reducing the monitor window is input, and the controller receives a video signal from the mobile terminal corresponding to the information and controls the second screen image to be reduced within the reduced monitor window using the video signal.
