6. The content sharing method of claim 5, wherein the first button indicates identification information of the first user terminal, and the second button indicates identification information of the second user terminal.

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

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

9. 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 first 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 to the display device;

transmitting a first transparent layer output request to the display device to allow the display device to distinguish between a first button or a second button;

receiving second information included in a second transparent layer of a second user terminal from the display device based on a selection of the second information of the second user terminal on the display device; and

overlapping the second information on the displayed content,

wherein the transmitting of the first handwritten information to the display device comprises determining a property of the first transparent layer and transmitting the first handwritten information to the display device according to the property of the first transparent layer,

wherein the second information received from the display device comprises

second handwritten information that is input to the second user terminal, and

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

10. The content sharing method of claim 9, wherein the overlapping of the second information received from the display device on the displayed content comprises replacing the first handwritten information with the second information received from the display device.

11. The content sharing method of claim 9, wherein the first handwritten information further comprises a first identification information of the first user terminal.

12. 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.

13. A non-transitory computer-readable recording medium having recorded thereon a computer program for executing the method of claim 9.

14. A display device for sharing content with a plurality of user terminals, the display device comprising:

a display configured to display the content;

a user input interface configured to receive a user input;

a transceiver configured to receive information included in a transparent layer from each of the plurality of user terminals comprising a first user terminal and a second user terminal; and

at least one processor configured to;

control the display to display a graphical user interface indicating the information on the display device,
