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 at least one or more buffer members which are disposed inside the adhesive member and have an elastic force.

2. The display device of claim 1, wherein the at least one or more buffer members are extended by a predetermined length in one direction.

3. 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.

4. 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.

5. 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.

6. 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 adhesive groove.

7. 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.

8. 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.

9. A method of manufacturing a display device, comprising:

preparing a guide frame which exposes a side surface of a display panel and includes a horizontal part supporting a bottom of the display panel and a vertical part extended from the horizontal part;

injecting a coupling member, which couples the guide frame to the display panel, onto the horizontal part; and

coupling the guide frame to the display panel,

wherein the coupling member is formed by combining at least one or more buffer members having an elastic force with an adhesive member providing adhesive strength.

10. The display device of claim 9, wherein the adhesive member is hardened at a normal temperature after a predetermine time elapses, hardened by applying heat at a predetermined temperature, or hardened by irradiating ultraviolet (UV).
