Abstract

A display apparatus includes a display apparatus comprising, a display panel comprising a front substrate and a back substrate, at least one structure disposed in the rear of the display panel, and a supporting film attached to the display panel and connected to at least one structure.

Claims

1. A display apparatus comprising:

a display panel comprising a front substrate and a back substrate;

at least one structure disposed in the rear of the display panel;

a light guide plate disposed behind the display panel;

a bracket disposed adjacent to the display panel;

a frame disposed behind the light guide plate;

a film joining portion disposed behind the display panel and the light guide plate;

a supporting film attached comprising a first area fixed to the display panel and connected to the at least one structure, the at least one structure comprising at least one of a bracket, a frame disposed adjacent to the bracket or a, a second area that extends from the first area and a third area that extends from the second area, a distal end of the supporting film in the third area being fixed to the film joining portion behind the display panel and the light guide plate; and

an adhesive layer disposed between on the distal end of the supporting film and at least one of the bracket, the frame or the film joining portion;

,

wherein at least one portion of the supporting film contacts with at least one portion of the at least one of the bracket, the frame or the film joining portion the film joining portion is fixed to the frame.

2. The display apparatus of claim 1, wherein the supporting film comprises a light transmissive material.

3. The display apparatus of claim 1, wherein the supporting film surrounds at least one structure the bracket.

4. The display apparatus of claim 1, wherein the film joining portion is connected to both ends of the supporting film fixed to an end of the third area.

5. The display apparatus of claim 1, wherein the film joining portion is connected to the frame.

6. The display apparatus of claim 1, wherein the supporting film comprises:

a first supporting film corresponding to a display area for displaying an image of the display panel; and

a second supporting film corresponding to a dummy area positioned outside the display area of the display panel.

7. The display apparatus of claim 6, wherein the transmittance of the first supporting film is higher than the transmittance of the second supporting film.

8. The display apparatus of claim 1, further comprising wherein the film joining portion comprises:

a first film joining portion connected to one end of the supporting film; and

a second film joining portion connected to the other another end of the supporting film.

9. The display apparatus of claim 1, wherein at least one structure the bracket is not attached to the supporting film.

10. The display apparatus of claim 1, wherein the supporting film the first area comprises a portion attached to the a rear surface of the back substrate.

11. The display apparatus of claim 1, wherein the supporting film the first area comprises a portion attached to the a front surface of the front substrate.

12. The display apparatus of claim 4, wherein the film joining portion comprises a first film joining portion and a second film joining portion and the first and second film joining portions are connected to each end of the supporting film.

13. The display apparatus of claim 1, wherein the frame includes at least one protrusion, and

wherein the display apparatus further comprisingcomprises at least one optical sheet which includes at least one hole corresponding to the at least one protrusion.

14. The display apparatus of claim 1, further comprising:

a backlight unita light guide plate disposed on an edge ofin front of the frame, the edge comprising at least one of each side or bottom of the frame; and

a light source positioned near a side of the light guide panel.

15. The display apparatus of claim 1, further comprising:

a side cover including a sidewall disposed at a side of the display panel; and

a back cover located at a rear of the display panel,

wherein the side cover is connected to the frame and the back cover is connected to the side cover.

16. The display apparatus of claim 1, wherein the at least one bracket is provided adjacent to a side of the frame.

19. The display apparatus of claim 1, wherein the adhesive layer is disposed between the supporting film and the frame.

17. A display apparatus comprising:
