Abstract

An LCD device having a wire holder are disclosed, in which a wire from a lamp is efficiently fixed to an inverter through a lead-out space formed at the edge of one side of a bottom cover. The LCD device has a bottom cover with bottom and lateral sides extending from the bottom, provided with a groove formed by partially cutting the bottom and the lateral sides at the edge, a light guide plate in the bottom cover, a lamp between one side of the light guide plate and one side of the bottom cover, a wire connected to both ends of the lamp and extending along the side of the bottom cover to the groove, a wire holder to which the wire is inserted to collect the wire in the groove, limiting motion of the wire, and an LCD panel arranged on the light guide plate.

Claims (21)

1. An LCD device comprising:

a bottom cover having a bottom and lateral sides extending from the bottom, provided with a groove in the bottom and the lateral sides at the edge;

a light guide plate received in the bottom cover;

a lamp arranged between one side of the light guide plate and one side of the bottom cover;

a wire connected to both ends of the lamp and extended along the side of the bottom cover to be collected in the groove;

a wire holder to which the wire is inserted to collect the wire in the groove, limiting motion of the wire, the wire holder being disposed at the inner side surface, a part of the lower surface of the bottom cover being inserted to the wire holder to disposed the wire holder thereto, thereby the wire holder holds the wire arranged along the inner peripheral region of the bottom; and

an LCD panel arranged on the light guide plate,

wherein the wire holder includes a main body, a protrusion protruded from the main body to be perpendicular to the groove, and a holder clamp extending from the main body to be perpendicular to the groove and the protrusion,

wherein the side surface of the bottom cover is partially cut and the size of the cut portion is substantially same as size of the width of the protrusion so that the protrusion is inserted to the cut portion of the bottom cover to assemble the protrusion with the bottom cover.

2. The LCD device as claimed in claim 1 , wherein the protrusion has the substantially same thickness as a side thickness of the bottom cover.

3. The LCD device as claimed in claim 1 , wherein the main body is provided with a wire groove to which the wire is inserted.

4. The LCD device as claimed in claim 1 , wherein the main body has one end extended to adjoin the edge of the bottom cover.

5. The LCD device as claimed in claim 1 , wherein the wire holder is formed of polycarbonate (PC).

6. The LCD device as claimed in claim 1 , wherein the main body in z direction has one side cut to expose a portion of the wire groove.

7. A wire holder for holding a wire in a liquid crystal display device, the wire holder comprising:

a main body provided with a wire groove in which the wire is inserted;

a protrusion projected from the main body, the protrusion being extended to be perpendicular to the wire groove, the protrusion being inserted to a cut portion of a bottom cover of the liquid crystal display device; and

a holder clamp protruded from the main body and the protrusion, the holder clamp being extended to be perpendicular to the wire groove and the protrusion, the holder clamp including a fitting groove into which the lower surface of the bottom cover is inserted.

8. The wire holder as claimed in claim 7 , wherein the wire holder is formed of polycarbonate (PC).

9. The wire holder as claimed in claim 7 , wherein the main body in z direction has one side cut to expose a portion of the wire groove.

10. The LCD device as claimed in claim 7 , wherein the main body is extended to the corner of the bottom cover to curve smoothly the wire at the corner of the bottom cover.
