Abstract

A display device includes a display panel including an upper substrate and a lower substrate facing and coupled to a rear surface of the upper substrate, a guide frame supporting the display panel, and a coupling member coupling the guide frame to the display panel. The coupling member includes an adhesive member providing adhesive strength and at least one or more buffer members which are disposed inside the adhesive member and have an elastic force. Accordingly, the display device can absorb an impact applied to the display panel, thus enhancing the stability of the display panel.

Claims

1. A display device, comprising:

a display panel including an upper substrate and a lower substrate facing and coupled to a rear surface of the upper substrate;

a guide frame supporting the display panel; and

a coupling member coupling the guide frame to the display panel,

wherein the coupling member comprises an adhesive member providing adhesive strength and a plurality of elastic buffer members each of which have an elastic force and are disposed inside the adhesive member, wherein the plurality of elastic buffer members are of different length and are irregularly intermingled in the adhesive member, wherein at least one or more elastic buffer members of the plurality of elastic buffer members have circular shaped cross sections.

2. The display device of claim 1, wherein the guide frame exposes a side surface of the display panel, and comprises a horizontal part supporting a bottom of the display panel and a vertical part extended from the horizontal part, and the display panel extends to and overlaps with the vertical part of the guide frame.

3. The display device of claim 1, wherein the guide frame comprises a side part covering a side surface of the display panel, the side part being provided to the same height as the display panel and not being provided at a top of the display panel.

4. The display device of claim 1, wherein the guide frame comprises a prevention jaw formed to protrude from a horizontal part that supports a bottom of the display panel.

5. The display device of claim 1, wherein the guide frame comprises an adhesive groove concavely formed in a horizontal part that supports a bottom of the display panel, and receiving the coupling member.

6. The display device of claim 1, wherein the coupling member is formed of a light-absorbing material or in a light-absorbing color, and prevents the light from passing through the coupling member.

7. The display device of claim 1, wherein the adhesive member is one of urethane-based material, acrylic-based material, epoxy-based material, and cyanoacrylate-based material.

8. The display device of claim 1, further comprises:

a cover member having a first coupling part concavely formed for supporting an inner side surface of the guide frame; and

wherein the guide frame includes a second coupling part protrudingly formed corresponding to the first coupling part.

9. The display device of claim 1, wherein the at least one or more elastic buffer members of the coupling member extend in one direction and are pipe shaped.

10. A display device, comprising:

a display panel including an upper substrate and a lower substrate facing and coupled to a rear surface of the upper substrate;

a guide frame supporting the display panel; and

a coupling member coupling the guide frame to the display panel,

wherein the coupling member comprises an adhesive member providing adhesive strength and a plurality of elastic buffer members each of which have an elastic force and are disposed inside the adhesive member, wherein the plurality of elastic buffer members are of different length and are irregularly intermingled in the adhesive member, wherein at least one or more elastic buffer members of the plurality of elastic buffer members have hollow ring shaped cross sections.

13. The display device of claim 10, wherein the at least one or more elastic buffer members of the coupling member extend in one direction and are pipe shaped.

11. A display device, comprising:

a display panel including an upper substrate and a lower substrate facing and coupled to a rear surface of the upper substrate;

a guide frame supporting the display panel; and

a coupling member coupling the guide frame to the display panel,

wherein the coupling member comprises an adhesive member providing adhesive strength and a plurality of elastic buffer members each of which have an elastic force and are disposed inside the adhesive member, wherein the plurality of elastic buffer members are of different length and are irregularly intermingled in the adhesive member, wherein at least one or more elastic buffer members of the plurality of elastic buffer members have angular shaped cross sections.

12. The display device of claim 11, wherein the at least one or more elastic buffer members have triangular shaped cross sections.

14. The display device of claim 11, wherein the at least one or more elastic buffer members of the coupling member extend in one direction and are pipe shaped.

15. A display device, comprising:

a display panel including;

an upper substrate,

a lower substrate facing and coupled to a rear surface of the upper substrate,

a liquid crystal layer between the lower substrate and upper substrate, and

a plurality of pixels adjusting light transmittance of the liquid crystal layer in accordance with corresponding data voltages applied to the plurality of pixels;

a guide frame supporting the display panel; and

a coupling member coupling the guide frame to the display panel,

wherein the coupling member comprises an adhesive member and at least one or more elastic buffer members disposed inside the adhesive member;

wherein the guide frame exposes a side surface of the display panel, and comprises a horizontal part supporting a bottom of the display panel and a vertical part extended from the horizontal part, and the display panel extends at least to and overlaps with the vertical part of the guide frame.

16. The display device of claim 15, further comprising:

a cover member having a first coupling part concavely formed for supporting an inner side surface of the guide frame; and

wherein the guide frame includes a second coupling part protrudingly formed corresponding to the first coupling part.

17. The display device of claim 15, wherein the guide frame comprises an adhesive groove concavely formed in a horizontal part that supports a bottom of the display panel, and receiving the coupling member.

18. The display device of claim 15, wherein the coupling member is formed of a light-absorbing material or in a light-absorbing color, and prevents the light from passing through the coupling member.
