Abstract

A display device including a display panel displaying images, a protective member disposed on a front surface of the display panel and protecting the display panel and a support frame supporting both the display panel and the protective member The support frame includes a guide part protruded in a direction perpendicular to a plate surface of the protective member and fixing the protective member such that the protective member is prevented from moving in a direction parallel to the plate surface. The support frame is adhered to edges of the protective member.

Claims

1. A display device comprising:

a display panel displaying images;

a protective member disposed on a front surface of the display panel and protecting the display panel; and

a support frame supporting and contacting a lower surface of the display panel and supporting and contacting a lower surface of the protective member,

wherein the support frame comprises a guide part protruded in a direction perpendicular to a plate surface of the protective member and fixing the protective member such that the protective member is prevented from moving in a direction parallel to the plate surface, and the support frame is adhered to edges of the protective member.

2. The display device of claim 1, further comprising an adhesive member interposed between the edges of the protective member and the support frame and adhering the edges of the protective member and the support frame to each other.

3. The display device of claim 2, wherein the support frame further comprises

a first support part supporting a surface of the display panel;

and

a second support part supporting a surface of the protective member.

4. The display device of claim 3, wherein the first support part and the second support part form a step difference such that the protective member is spaced apart from the display panel.

5. The display device of claim 4, wherein an interval between the protective member and the display panel is in a range of about 0.2 millimeter (mm) to about 0.6 millimeter (mm).

6. A display device comprising:

a display panel displaying images;

a protective member disposed on a front surface of the display panel and protecting the display panel; and

a support frame supporting the display panel and the protective member together,

wherein the support frame comprises a first support part contacting a lower surface of the display panel and a second support part supporting a lower surface of the protective member.

7. The display device of claim 6, wherein the support frame further comprises a guide part protruded in a direction perpendicular to a plate surface of the protective member and fixing the protective member such that the protective member is prevented from moving in a direction parallel to the plate surface.

8. The display device of claim 7, wherein the guide part is disposed adjacent to a corner of the protective member.

9. The display device of claim 7, wherein the guide part is disposed adjacent to a side surface of the protective member.

10. The display device of claim 6, further comprising an adhesive member interposed between edges of the protective member and the support frame and adhering the edges of the protective member and the support frame to each other.

11. The display device of claim 10, wherein the adhesive member has a thickness of about 0.1 mm to about 0.5 mm.

12. The display device of claim 6, wherein the first support part and the second support part form a step difference.

13. The display device of claim 12, wherein the second support part is positioned higher than the display panel by about 0.1 mm to about 0.5 mm.

14. The display device of claim 6, wherein an interval between the protective member and the display panel is in a range of about 0.2 mm to about 0.6 mm.

15. The display device of claim 6, wherein the protective member comprises a transparent material.

16. The display device of claim 6, wherein the display panel is a liquid crystal display panel.

21. The display device of claim 6, wherein the lower surface of the display panel is a surface of the display panel disposed furthest from an outside along a viewing direction and the lower surface of the protective member is a surface of the protective member disposed furthest from the outside along the viewing direction.

17. An information processing apparatus comprising:

a housing; and

a display device disposed in the housing, the display device comprising;

a display panel displaying images;

a protective member disposed on a front surface of the display panel and protecting the display panel; and

a support frame supporting both the display panel and the protective member;

wherein the support frame comprises a first support part contacting a lower surface of the display panel and a second support part supporting a lower surface of the protective member, the first support part and the second support part forming a step difference.

18. The information processing apparatus of claim 17, wherein the protective member contacts a display surface of the housing.

19. The information processing apparatus of claim 17, wherein the protective member is fixed to the display device and is spaced from the display panel by about 0.2 mm to about 0.6 mm.

20. The information processing apparatus of claim 17, wherein the housing is a part of a mobile telephone.

22. The information processing apparatus of claim 17, wherein the lower surface of the display panel is a surface of the display panel disposed furthest from an outside along a viewing direction and the lower surface of the protective member is a surface of the protective member disposed furthest from the outside along the viewing direction.
