Abstract

A liquid crystal display device includes a liquid crystal panel having a display area, a light source joined with the liquid crystal panel, a first frame coupled to a surface of the light unit and sides of the liquid crystal panel, a second frame coupled to edges of the liquid crystal panel and sides of the first support frame, an outer casing, and a fastening part joining together the first support frame, the second support frame, and the outer casing through the sides of the first support frame, the second support frame, and the outer casing.

Claims

1. A liquid crystal display device comprising:

a liquid crystal panel including a display area;

a light source joined with the liquid crystal panel;

a first frame coupled to a surface of the light unit and sides of the liquid crystal panel;

a second frame coupled to edges of the liquid crystal panel and sides of the first support frame;

an outer casing; and

a fastening part joining together the first support frame, the second support frame, and the outer casing through the sides of the first support frame, the second support frame, and the outer casing.

2. The liquid crystal device according to claim 1, wherein the fastening part includes a screw hole.

3. The liquid crystal device according to claim 1, wherein the sides of the first support frame, the second support frame, and the outer casing are substantially perpendicular to the viewing direction of the display device.

4. The liquid crystal device according to claim 1, wherein the first frame supports the light source.

5. The liquid crystal device according to claim 1, wherein the second frame protects the liquid crystal panel.

6. A portable computer comprising:

a liquid crystal display device having a display surface and a first plurality of side surfaces;

a body having an input device;

a cover, coupled to an edge of the body, having a second plurality of side surfaces; and

a fastening unit attaching the first plurality of side surfaces of the liquid crystal display device to the second plurality of side surfaces of the cover, the liquid crystal display device being mounted to the cover.

7. The portable computer according to claim 6, wherein the fastening unit includes a screw hole through the first and second side surfaces of the liquid crystal display device and cover, respectively, and a screw in the screw hole.

8. The portable computer according to claim 6, wherein the fastening unit incudes an adhesive joining the first plurality of side surfaces of the liquid crystal display device to the second plurality of side surfaces of the cover.

9. A portable computer comprising:

a liquid crystal display device having a first side surface;

a body having an input device;

a cover joined with the body and having a second side surface; and

a fastening unit joining together the liquid crystal display device and the cover through the first and second side surfaces of the liquid crystal display device and the cover, respectively.

10. A liquid crystal display device comprising:

a first support frame having a first fastening member at a side surface of the first support frame;
