Display apparatus

1. A display apparatus comprising:

a display module deformable between a flat surface state and a curved surface state including a flexible display panel on which an image is displayed;

a top chassis at a front of the flexible display panel; and

a bottom chassis at a rear of the flexible display panel,

wherein the bottom chassis includes:

a rear panel forming a rear surface of the bottom chassis, and

one pair of side frames forming both side surfaces of the bottom chassis, the one pair of side frames being formed to accommodate both side ends of the rear panel, and

wherein when the display module deforms from the flat surface state to the curved surface state, the one pair of side frames move away from the both side ends of the rear panel, respectively, such that the both side ends of the rear panel are spaced further from the both side surfaces of the bottom chassis than in the flat surface state.

2. The display apparatus of claim 1 , wherein the one pair of side frames comprise side guide grooves, respectively, that are extended in upper and lower side directions to correspond to the both side ends of the rear panel, respectively, such that the both side ends of the rear panel are movably accommodated in the side guide grooves, respectively.

3. The display apparatus of claim 2 , wherein:

the bottom chassis comprises an upper frame forming an upper portion of the bottom chassis and a lower frame forming a lower portion of the bottom chassis; and

the upper frame and the lower frame movably support an upper end of the rear panel and a lower end of the rear panel, respectively.

4. The display apparatus of claim 3 , wherein:

the upper frame includes an upper guide groove configured to movably support the upper end of the rear panel; and

the lower frame includes a lower guide groove configured to movably support the lower end of the rear panel.

5. The display apparatus of claim 4 , wherein the upper frame and the lower frame each includes a plurality of slits that are extended in upper and lower side directions while laterally spaced apart from each other.

6. The display apparatus of claim 4 , further comprising a plurality of insertion members inserted into the upper guide groove and the lower guide groove to accommodate the upper end of the rear panel and the lower end of the rear panel.

7. The display apparatus of claim 6 , wherein some of the plurality of insertion members have inverse-U shaped cross sections to be inserted between the upper end of the rear panel and the upper guide groove and the remaining have U shaped cross sections to be inserted between the lower end of the rear panel and the lower guide groove.

8. The display apparatus of claim 6 , wherein the plurality of insertion members are made of lubricative resin.

9. The display apparatus of claim 6 , wherein the plurality of insertion members are disposed side by side in a width direction of the bottom chassis to be inserted into the upper guide groove and the lower guide groove.

10. The display apparatus of claim 1 , further comprising a driving apparatus configured to deform the display module to be in the flat surface state or in the curved surface state.

11. A display apparatus comprising:

a display panel that is deformable to be in a flat surface state or in a curved surface state, wherein the display panel is included in a display which includes a top chassis at a front of the display panel, and a bottom chassis at a rear of the display panel, the display panel being configured to display an image;

wherein the bottom chassis includes:

a rear panel forming a rear surface of the bottom chassis,

an upper frame having an upper guide groove configured to be formed to accommodate an upper end of the rear panel, and

a lower frame having a lower guide groove configured to be formed to accommodate a lower end of the rear panel.

12. The display apparatus of claim 11 , wherein the upper frame and the lower frame each includes a plurality of slits that are extended in upper and lower directions while laterally spaced apart from each other.

13. The display apparatus of claim 11 , further comprising a plurality of insertion members that are inserted into the upper guide groove and the lower guide groove to accommodate the upper end and the lower end of the rear panel.

14. The display apparatus of claim 13 , wherein some of the plurality of insertion members have inverse U shaped cross sections to be inserted between the upper end of the rear panel and the upper guide groove and the remaining have U shaped cross sections to be inserted between the lower end of the rear panel and the lower guide groove.

15. The display apparatus of claim 13 , wherein the plurality of insertion members are made of lubricative resin.
