Abstract

A liquid crystal display device is disclosed. In one embodiment, the device includes: a panel having a first substrate and a second substrate with a liquid crystal layer interposed therebetween, and a first polarizing plate and a second polarizing plate, respectively, attached on the exterior surfaces of the first substrate and the second substrate. The device may further include a driving chip installed in a boundary of the first substrate at the opposite surface of the first substrate onto which the first polarizing plate is attached, wherein the first polarizing plate covers the boundary of the first substrate and has a cut portion corresponding to the first substrate in which the driving chip is installed.

Claims (13)

1. A liquid crystal display device comprising:

a panel comprising a first substrate and a second substrate with a liquid crystal layer interposed therebetween, and a first polarizing plate and a second polarizing plate, respectively, attached on the exterior surfaces of the first and second substrates, wherein the first substrate comprises top and bottom surfaces opposing each other, wherein the first polarizing plate comprises top and bottom surfaces opposing each other, and wherein the top surface of the first polarizing plate contacts the bottom surface of the first substrate;

a driving chip formed on the top surface of the first substrate; and

a backlight unit configured to irradiate backlight to the panel,

wherein the first polarizing plate has a cut portion formed substantially directly below the driving chip, and wherein the cut portion is covered by the bottom surface of the first substrate.

2. The liquid crystal display device of claim 1 , wherein the driving chip is attached onto the first substrate with a first double-sided tape interposed therebetween.

3. The liquid crystal display device of claim 1 , wherein the cut portion has a rectangular shape, a circular shape or other polygonal shape.

4. The liquid crystal display device of claim 1 , further comprising: a mold frame configured to surround the backlight unit,

wherein the first polarizing plate is attached onto the mold frame and the backlight unit with a second double-sided tape interposed therebetween.

5. The liquid crystal display device of claim 1 , further comprising: a flexible circuit substrate connected to the first substrate.

6. The liquid crystal display device of claim 1 , wherein the first substrate comprises a linear edge portion corresponding to the width or length of the first polarizing plate, wherein the first polarizing plate does not cover the linear edge portion of the first substrate, and wherein the driving chip is not formed directly above the linear edge portion.

7. The liquid crystal display device of claim 1 , wherein the first substrate comprises a linear edge portion corresponding to the width or length of the first polarizing plate, wherein the first polarizing plate does not cover the linear edge portion of the first substrate, and wherein the cut portion of the first polarizing plate is not formed directly below the linear edge portion of the first substrate.

8. The liquid crystal display device of claim 1 , wherein the first polarizing plate has a width and a length, and wherein the cut portion has a size less than the width or length of the first polarizing plate.
