wherein the reinforcing member comprises a thin plate having characteristics of rigidity and flexibility, and polyethylene terephthalate (“PET”).
2. The gasket of claim 1 , wherein the reinforcing member is disposed substantially in an “L” shape, and contacts a bottom surface and one side of the elastic member.
3. The gasket of claim 2 , wherein the reinforcing member is a single and continuous unit.
4. The gasket of claim 1 , wherein the reinforcing member is disposed substantially in a “U” shape, and contacts a bottom surface and opposing sides of the elastic member.
5. The gasket of claim 4 , wherein the reinforcing member is a single and continuous unit.
6. The gasket of claim 1 , wherein the conductive member comprises non conductive fabric plated with a conductive material.
7. The gasket of claim 6 , wherein the conductive member is disposed such that end portions of the conductive member overlap each other and a whole of a bottom of the elastic member.
8. The gasket of claim 1 , wherein the bottom portion of the reinforcing member covers substantially entire upper surface of a bottom portion of the conductive member.
9. A gasket comprising:
an elastic member absorbing an external shock;
a conductive member contacting an outer surface of the elastic member and surrounding the elastic member;
a reinforcing member disposed between the elastic member and the conductive member, the reinforcing member including:
a bottom portion extending parallel to a bottom surface of the conductive member; and
a side portion extending inclined from the bottom portion and parallel to a side surface of the conductive member; and
a conductive adhesive disposed on and contacting an outer surface of the conductive member.
10. A screen spacer comprising:
an elastic member configured to absorb an external shock;
a reinforcing member disposed on one side of the elastic member;
a first adhesion member combining the reinforcing member with the elastic member; and
a second adhesion member disposed directly on an outer surface of the reinforcing member opposite to the elastic member, such that the second adhesion member is an outermost layer of the screen spacer.
11. The screen spacer of claim 10 , wherein the reinforcing member comprises a thin plate with fixity.
12. The screen spacer of claim 10 , wherein the elastic member comprises sponge.
13. A display device, comprising:
a display panel displaying images;
a driving circuit substrate supplying a driving signal to the display panel;
a chassis surrounding an edge of the display panel; and
a gasket attached to the driving circuit substrate and contacting the chassis, and
wherein the gasket comprises:
an elastic member absorbing an external shock;
a conductive member contacting an outer surface of the elastic member, such that the conductive member surrounds the elastic member; and
a reinforcing member disposed between the elastic member and the conductive member, the reinforcing member including:
a bottom portion extending parallel to a bottom surface of the conductive member; and
a side portion extending inclined from the bottom portion and parallel to a side surface of the conductive member,
wherein the gasket grounds the driving circuit substrate and the chassis.
