Abstract

A liquid crystal display device includes a cover bottom, a support main over the cover bottom, a backlight unit surrounded by the support main, a liquid crystal panel over the backlight unit and including first and second substrates with a liquid crystal layer interposed therebetween, a driving circuit on an edge portion of the first substrate, a printed circuit board connected to the driving circuit through a connection means and bent toward one of a side surface of the support main and a rear surface of the cover bottom, and an adhesive tape covering edges of a front surface of the liquid crystal panel and including a conductive layer contacting the liquid crystal panel and the driving circuit, wherein the conductive layer is electrically connected to one of the cover bottom and the printed circuit board.

Claims (18)

1. A liquid crystal display device, comprising:

a cover bottom;

a support main over the cover bottom;

a backlight unit surrounded by the support main;

a liquid crystal panel over the backlight unit and including first and second substrates with a liquid crystal layer interposed therebetween;

a driving circuit on an edge portion of the first substrate;

a printed circuit board connected to the driving circuit through a connection means and bent toward one of a side surface of the support main and a rear surface of the cover bottom; and

an adhesive tape covering edges of a front surface of the liquid crystal panel and including a conductive layer contacting the liquid crystal panel and the driving circuit,

wherein the conductive layer is electrically connected to one of the cover bottom and the printed circuit board.

2. The device according to claim 1 , further comprising a protection pad at a side of the driving circuit.

3. The device according to claim 1 , wherein the adhesive tape includes first, second, third and fourth parts and has a rectangular frame shape.

4. The device according to claim 3 , wherein the conductive layer is formed on an inward portion of the first part along a length direction of the first part and has a wider width than the driving circuit.

5. The device according to claim 4 , wherein the first part of the adhesive tape is partially wider than the third and fourth parts of the adhesive tape.

6. The device according to claim 4 , wherein the first part of the adhesive tape extends onto the rear surface of the cover bottom.

7. The device according to claim 6 , wherein the first part of the adhesive tape covers the printed circuit board.

8. The device according to claim 1 , wherein the conductive layer corresponds to a side of the liquid crystal panel connected to the printed circuit board.

9. The device according to claim 1 , wherein the conductive layer includes aluminum.

10. The device according to claim 1 , wherein the adhesive tape includes a base film of a polyethylene terephthalate (PET) resin and an adhesive material layer.
