3. The display device of claim 2, wherein the user command intends to display the modified monitor screen image on the second orientation direction of the monitor window based on the modified mobile screen image.

4. The display device of claim 3, wherein the first orientation direction of the monitor window is a horizontal direction and the second orientation direction of the monitor window is a vertical direction.

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

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

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

8. The display device of claim 1, wherein the controller is configured to display the monitor window at a 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.

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

10. The display device of claim 1, wherein in response to a user command for zooming-in the monitor screen image, the controller is configured to transmit information related to the user command to the mobile terminal, and receive a video signal from the mobile terminal corresponding to the information while a size of the monitor window to be maintained.

11. The display device of claim 1, wherein in response to a user command for zooming-out the monitor screen image, the controller is configured to transmit information related to the user command to the mobile terminal, and receive a video signal from the mobile terminal corresponding to the information while a size of the monitor window is maintained.

12. The display device of claim 1, wherein in response to a user command for enlarging the monitor window, the controller is configured to control the monitor window to be enlarged and control the monitor screen image to be enlarged within the enlarged monitor window while a zoom level of the monitor screen image is not changed.

13. The display device of claim 1, wherein in response to a user command for enlarging the monitor window, the controller is configured to control the monitor window to be enlarged and transmit information to the mobile terminal, the information indicating the user command for enlarging the monitor window is input, and the controller is configured to receive a video signal from the mobile terminal corresponding to the information and control the monitor screen image to be enlarged within the enlarged monitor window using the video signal.

14. The display device of claim 1, wherein in response to a user command for reducing the monitor window, the controller is configured to control the monitor window to be reduced and control the monitor screen image to be reduced within the reduced monitor window while a zoom level of the monitor screen image is not changed.
