10. The method as claimed in claim 9, wherein the state information indicates at least one of a power on/off state, a battery charging state and an opening and closing state of the shutter glasses.

11. The method as claimed in claim 9, wherein, if the received state information indicates the shutter glasses are turned off while in the 3D display mode, the performing the one of the changing from the 3D display mode to the 2D display mode, and the displaying of the first message automatically changes the 3D display mode to the 2D display mode.

12. The method as claimed in claim 9, wherein, if the received state information indicates the shutter glasses are turned on while in the 2D display mode, the performing the one of the changing from the 2D display mode to the 3D display mode and the displaying of the second message automatically changes from the 2D display mode to the 3D display mode.

13. The method as claimed in claim 9 further comprising displaying a third message requesting the shutter glasses to be turned on if the received state information indicates the shutter glasses are turned off while in the 3D display mode.

14. The method as claimed in claim 13, further comprising terminating the displaying of the third message if new state information is received indicating that the shutter glasses are turned on after receiving the received state information indicating that the shutter glasses are turned off.

15. The method as claimed in claim 9, wherein, if the received state information indicates the shutter glasses are turned on while in the 2D display mode, the performing the one of the changing from the 2D display mode to the 3D display mode and the displaying of the second message displays a message asking whether to change to the 3D display mode.

16. The method as claimed in claim 9, wherein the shutter glasses transmit the state information based on at least one of a predetermined time interval or whether a request for the state information is received.

17. The method as claimed in claim 9, wherein the 3D display mode is a mode in which a left-eye image and a right-eye image of a 3D image are displayed alternately on a screen, and the 2D display mode is a mode in which the left-eye image and the right-eye image are separately displayed on the screen.

18. A display apparatus for displaying a three-dimensional (3D) image, the display apparatus comprising:

a communication interface which receives state information regarding shutter glasses from the shutter glasses; and

a controller which is operable to change a play mode based on the received state information and operable to control a displaying of a message for changing the play mode based on the received state information.

19. The display apparatus as claimed in claim 18, wherein the state information indicates at least one of a power on/off state, a battery charging state and an opening and closing state of the shutter glasses.

20. The display apparatus as claimed in claim 18, wherein, if the received state information indicates the shutter glasses are tuned off while the 3D image is being played, the controller automatically pauses playing the 3D image.

21. The display apparatus as claimed in claim 18, wherein, if the received state information indicates the shutter glasses are turned on while playing of the 3D image is paused, the controller automatically plays the 3D image.

22. The display apparatus as claimed in claim 18, wherein, if the received state information indicates the shutter glasses are turned off while the 3D image is being played, the controller controls a displaying of a request message requesting the shutter glasses to be turned on.

23. The display apparatus as claimed in claim 22, wherein, if new state information is received indicating the shutter glasses are turned on after receiving the received state information indicating that the shutter glasses are turned off, the controller terminates the displaying of the request message.
