a housing;

a roller located within the housing;

a display panel;

a plate at a rear of the display panel, wherein the plate comprises a plurality of openings; and

an adhesive layer between the plate and the display panel,

wherein a resin is disposed to fill in the plurality of openings and cover a rear of the plate, and

wherein the display panel and the plate are wound on the roller.

2. The display device of claim 1, wherein the resin is continuously disposed from the rear of the plate through the plurality of openings of the plate.

3. The display device of claim 1, wherein the resin is further disposed between the plate and the adhesive.

4. The display device of claim 3, wherein the resin is continuously disposed from the rear of the plate through the plurality of openings of the plate and to an area between the plate and the adhesive layer.

5. The display device of claim 3, wherein the plate is fully encapsulated in the resin.

6. The display device of claim 1, wherein the resin covers a rear of the plate such that the rear of the plate is not externally exposed from the resin.

7. The display device of claim 1, wherein the adhesive layer fixes the resin to the display panel.

8. The display device of claim 1, further comprising:

an upper assembly; and

a lift assembly comprising a plurality of arms and configured to raise and lower the upper assembly,

wherein the display panel, plate, adhesive layer, and resin are integrally formed and coupled to the upper assembly such that the display panel is extended from the housing by the lift assembly.

9. The display device of claim 1, wherein the resin is flexible such that it is wound around the roller with the display panel and the plate.

10. The display device of claim 9, wherein the resin is comprised of urethane or rubber.
