Abstract

A display apparatus includes a substrate, a display unit on a first surface of the substrate, and a protection film on a second surface, opposite the first surface, of the substrate. The protection film includes a first adhesive layer having a first surface that faces the second surface of the substrate; a protection film base having a first surface that faces a second surface, opposite the first surface, of the first adhesive layer; and a light blocking layer having a first surface that faces a second surface, opposite the first surface of the protection film base.

First claim

What is claimed is:

1. A display apparatus, comprising:
a substrate;
a display device on a first surface of the substrate, the display device including a pixel electrode; and
a protection film on a second surface, opposite the first surface, of the substrate, wherein the protection film includes:
a first adhesive layer having a first surface that faces the second surface of the substrate;
a protection film base having a first surface that faces a second surface, opposite the first surface, of the first adhesive layer; and
a light blocking layer having a first surface that faces a second surface, opposite the first surface, of the protection film base, the light blocking layer overlapping with an entire area of the pixel electrode and blocking external light from background, wherein the protection film base is between the first adhesive layer and the light blocking film.

2. The display apparatus as claimed in claim 1 , wherein the light blocking layer blocks visible light.

3. The display apparatus as claimed in claim 1 , further comprising a heat sink film adjacent a second surface, opposite the first surface, of the light blocking layer.

4. The display apparatus as claimed in claim 3 , wherein the protection film further includes a second adhesive layer between the light blocking layer and the heat sink film.

5. The display apparatus as claimed in claim 1 , further comprising a cushion layer adjacent a second surface, opposite the first surface, of the light blocking layer.

6. The display apparatus as claimed in claim 5 , wherein the protection film further includes a second adhesive layer between the light blocking layer and the cushion layer.

7. The display apparatus as claimed in claim 1 , wherein
the substrate has a display area and a peripheral area outside the display area,
the display device overlaps the display area,
the display apparatus further includes a printed circuit board mounted on a portion of the peripheral area including a first edge portion of the substrate, and
a length of the first edge portion is equal to a width of a part of the printed circuit board mounted on the first edge portion.

8. The display apparatus as claimed in claim 1 , wherein the substrate has a display area and a peripheral area outside the display area, and the display device overlapping the display area, the display apparatus further comprising:
an electronic chip mounted on a portion of the peripheral area including a first edge portion of the substrate; and
a compensating film having a first surface that contacts the first surface of the substrate, the compensating film covering the first surface of the substrate between the display area and the first edge portion.

9. The display apparatus as claimed in claim 8 , wherein a thickness of the compensating film is equal to a thickness of the electronic chip.

10. The display apparatus as claimed in claim 8 , wherein the compensating film completely covers the top surface of the substrate which is between the display area and the first edge portion, except for the portion to which the electronic chip is attached.

11. The display apparatus as claimed in claim 8 , further comprising
a printed circuit board attached to the portion of the peripheral area having the first edge portion, wherein:
the printed circuit board does not overlap the electronic chip, and
the compensating film covers a portion of the printed circuit board that overlaps the substrate.

12. The display apparatus as claimed in claim 11 , wherein a distance from the first surface of the substrate to a second surface, opposite the first surface, of the compensating film is uniform in an entire portion of the compensating film.

13. The display apparatus as claimed in claim 1 , wherein the first surface of the first adhesive layer has an uneven surface.

14. The display apparatus as claimed in claim 1 , wherein:
the substrate includes a first area, a second area, and a bending area between the first and second areas, the substrate being bent in the bending area
the substrate includes a display area and a peripheral area outside the display area,
the display area is in the first area,
the display device overlaps the display area, and
the peripheral area is in the first area, the second area, and the bending area.

15. The display apparatus as claimed in claim 14 , wherein the protection film is not in the bending area.

16. The display apparatus as claimed in claim 14 , further comprising
a bending protection layer extending in the first direction, the bending protection layer being in a portion of the first area, the bending area, and a portion of the second area.

17. The display apparatus as claimed in claim 14 , further comprising
a conductive layer having an uneven surface overlapping the bending area.

18. The display apparatus as claimed in claim 17 , wherein a width of the uneven surface is greater than a width of the bending area.

19. A display apparatus as claims in claim 14 , further comprising:
an electronic chip mounted on a portion of the peripheral area including a first edge portion of the substrate; and
a compensating film having a first surface that contacts the first surface of the substrate, the compensating film covering the first surface of the substrate between the bending area and the first edge portion.

20. A display apparatus as claimed in claim 19 , wherein a thickness of the compensating film is equal to a thickness of the electronic chip.
