6. The content sharing method of claim 4, further comprising:

displaying a first button for receiving an input of selecting the information received from the first user terminal and a second button for receiving an input of selecting the information received from the second user terminal on the display device,

wherein the overlapping of the transparent layer of the first user terminal, including the information received from the first user terminal, on the displayed content comprises;

when information for selecting the first button is input to the display device, overlapping the transparent layer of the first user terminal, including the information received from the first user terminal, on the displayed content.

7. The content sharing method of claim 6, further comprising:

receiving a transparent layer output request from the first user terminal; and

displaying the first and second buttons to be distinguished from each other when the transparent layer output request from the first user terminal is received.

8. The content sharing method of claim 6, wherein the first button indicates identification information of the first user terminal, and the second button indicates identification information of the second user terminal.

9. The content sharing method of claim 1, further comprising, if third handwritten information is input with respect to the transparent layer of the first user terminal that overlaps on the displayed content, transmitting the third handwritten information to the first user terminal.

31. A non-transitory computer-readable recording medium having recorded thereon a computer program for executing the method of claim 1.

10. A content sharing method performed by a first user terminal that outputs content to share a screen displayed on a display device, the content sharing method comprising:

displaying the content on the first user terminal;

overlapping a transparent layer of the first user terminal, including first handwritten information that is input to the first user terminal, on the displayed content

transmitting the first handwritten information included in the transparent layer of the first user terminal to the display device.

11. The content sharing method of claim 10, wherein the transmitting of the first handwritten information included in the transparent layer of the first user terminal to the display device comprises:

determining a property of the transparent layer of the first user terminal and transmitting the first handwritten information included in the transparent layer of the first user terminal to the display device according to the property of the transparent layer of the first user terminal, and

wherein the property of the transparent layer of the first user terminal indicates if the transparent layer of the first user terminal is shareable.

12. The content sharing method of claim 10, further comprising:

receiving information included in a transparent layer of a second user terminal among at least one terminal from the display device; and

overlapping the information received from the display device on the displayed content,

wherein the information received from the display device comprises second handwritten information that is input to the second user terminal.

13. The content sharing method of claim 12, wherein the overlapping of the information received from the display device on the displayed content comprises:

replacing the information included in the transparent layer of the first user terminal with the information received from the display device.

14. The content sharing method of claim 10, wherein the information included in the transparent layer of the first user terminal further comprises identification information of the first user terminal.

15. The content sharing method of claim 10, further comprising:

receiving third handwritten information that is input with respect to a transparent layer of the display device from the display device; and

updating the transparent layer of the display device that overlaps the content based on the third handwritten information.

32. A non-transitory computer-readable recording medium having recorded thereon a computer program for executing the method of claim 10.

16. A display device for sharing content with at least one user terminal, the display device comprising:

a display unit configured to display the content;

a communication unit configured to receive information included in a transparent layer of a first user terminal among the at least one user terminal from the first user terminal; and

a control unit configured to control the display unit to overlap the transparent layer of the first user terminal, including the information received from the first user terminal, on the displayed content,

wherein the at least one user terminal outputs the content to share a screen displayed on the display device.
