Abstract

A display apparatus is disclosed. In one aspect, the display apparatus includes a first display substrate including i) a first plane on which an image is displayed and ii) a second plane opposite to the first plane. The display apparatus also includes a second display substrate formed at least partially overlapping second plane, a guiding portion bent and connected to at least one of the first and second display substrates, a mold frame accommodating and supporting the second display substrate, and a flexible printed circuit board (FPCB) including i) a first area attached to the second plane of the first display substrate and ii) a second area connected to and guided by the guiding portion, wherein the FPCB is bent at least partially around the mold frame.

First claim

What is claimed is:

1. A display apparatus, comprising:
a first display substrate including a display area and a non-display area and further including i) a first surface on which an image is displayed, which is an outermost surface on a viewer side, and ii) a second surface opposite to the first plane;
a second display substrate overlapping the second surface;
a mold frame configured to support the second display substrate and to overlap the second surface in a plan view, an accommodation space being provided in the mold frame, wherein the mold frame includes a guide frame that is bent;
a flexible printed circuit board (FPCB) including i) a first area attached to the second surface of the first display substrate and ii) a second area connected to and guided by the guide frame, wherein the FPCB is bent at least partially around the mold frame; and
a printed circuit board (PCB) electrically contacting the FPCB and configured to provide a drive signal to the first display substrate, wherein the non-display area of the first display substrate protrudes more than the guide frame toward a direction from a center of the first display substrate to an edge of the first display substrate.

2. The display apparatus according to claim 1 , wherein a first position where substantially the maximum bending stress is generated against the FPCB is different from a second position where the maximum shear stress is generated against the FPCB.

3. The display apparatus according to claim 2 , wherein the first position is within the second area.

4. The display apparatus according to claim 3 , wherein the second position is within the first area.

5. The display apparatus according to claim 1 , wherein the mold frame further includes:
a bottom frame; and
a sidewall frame extending from an edge of the bottom frame towards the first display substrate,
wherein the guide frame is connected to an upper part of the sidewall frame and convexly bent towards the FPCB from the center of the first display substrate.

6. The display apparatus according to claim 5 , wherein the first display substrate further comprises:
an insulation substrate including a display area and a non-display area; and
a pad electrode disposed on the insulation substrate and attached to the FPCB and totally overlapping the non-display area, wherein the pad electrode protrudes in the same direction as that of the guide frame, and
wherein the guide frame protrudes more than the pad electrode.

7. The display apparatus according to claim 1 , wherein the first and second areas of the FPCB are spaced apart from each other by a predetermined distance.

8. The display apparatus according to claim 7 , wherein the guide frame and the first area of the FPCB are spaced apart from each other by a predetermined distance.

9. The display apparatus according to claim 1 , further comprising:
a top cover configured to accommodate the first display substrate, the second display substrate, the mold frame, the FPCB, and the PCB.

10. The display apparatus according to claim 9 , wherein the top cover comprises:
a bottom cover; and
a sidewall cover extending from an edge of the bottom cover and covering a side of the first display substrate.

11. The display apparatus according to claim 1 , further comprising:
a liquid crystal layer formed between the first display substrate and the second display substrate; and
a backlight unit accommodated in the mold frame.

12. A display apparatus, comprising:
a first display substrate including a display area and a non-display area and further including i) a first surface on which an image is displayed, which is an outermost surface on a viewer side, and ii) a second surface opposite to the first surface;
a second display substrate formed to be overlapping the second surface;
a guiding portion bent to be overlapping the second surface in a plan view and connected to at least one of the first and second display substrates;
a mold frame supporting the second display substrate, an accommodation space is provided in the mold frame;
a flexible printed circuit board (FPCB) including i) a first area attached to the second surface of the first display substrate and ii) a second area contacting and guided by the guiding portion, wherein the FPCB is bent at least partially around the mold frame, wherein the non-display area of the first display substrate protrudes more than the guide frame toward a direction from a center of the first display substrate to an edge of the first display substrate.

13. The display apparatus according to claim 12 , wherein a first position where substantially the maximum bending stress is generated against the FPCB is different from a second position where substantially the maximum shear stress is generated against the FPCB.

14. The display apparatus according to claim 13 , wherein the first position is within the second area.

15. The display apparatus according to claim 14 , wherein the second position is within the first area.

16. The display apparatus according to claim 12 , wherein the second display substrate comprises an insulation substrate,
wherein the guiding portion is formed adjacent to the insulation substrate and convexly bent toward the FPCB.

17. The display apparatus according to claim 12 , wherein the mold frame protrudes toward the FPCB, and wherein the guiding portion protrudes more than the mold frame.

18. The display apparatus according to claim 12 , wherein the mold frame supports the guiding portion.

19. The display apparatus according to claim 12 , further comprising:
a top cover accommodating the first display substrate, the second display substrate, the mold frame, and the FPCB.

20. The display apparatus according to claim 12 , wherein the guiding portion contacts the second surface of the first display substrate.

21. The display apparatus according to claim 1 , further comprising a pad electrode directly contacting the FPCB and the second surface of the first display substrate.
