Abstract

A liquid crystal display (LCD) device and a method of manufacturing the same are discussed. The LCD device according to an embodiment includes a first substrate and a second substrate bonded to each other, an inner black matrix and an outer black matrix disposed in the bezel area of the second substrate to be spaced apart from each other, and a liquid crystal layer disposed between the first substrate and the second substrate. A display area and a bezel area surrounding the display area are defined in the first substrate and the second substrate.

First claim

What is claimed is:

1 . A liquid crystal display (LCD) device comprising:
a first substrate and a second substrate bonded to each other, a display area and a bezel area surrounding the display area being defined therein; an inner black matrix and an outer black matrix disposed in the bezel area of the second substrate to be spaced apart from each other; and a liquid crystal layer disposed between the first substrate and the second substrate.

2 . The LCD device of claim 1 , wherein a certain gap is formed between the inner black matrix and the outer black matrix.

3 . The LCD device of claim 1 , wherein the inner black matrix and the outer black matrix are disposed on the second substrate to surround the display area.

4 . The LCD device of claim 1 , further comprising:
a ground line disposed in the bezel area of the first substrate.

5 . The LCD device of claim 4 , wherein the ground line of the first substrate is disposed to surround the display area of the first substrate.

6 . A liquid crystal display (LCD) device comprising:
a first substrate and a second substrate bonded to each other, a display area and a bezel area surrounding the display area being defined therein; a ground line disposed in the bezel area of the first substrate; an inner black matrix and an outer black matrix disposed in the bezel area of the second substrate to be spaced apart from each other; and a liquid crystal layer disposed between the first substrate and the second substrate.

7 . The LCD device of claim 6 , wherein a certain gap is formed between the inner black matrix and the outer black matrix.

8 . The LCD device of claim 6 , wherein the inner black matrix and the outer black matrix are independently spaced apart from each other with a certain gap therebetween.

9 . The LCD device of claim 6 , wherein the inner black matrix and the outer black matrix surround the display area of the second substrate.

10 . The LCD device of claim 6 , wherein the ground line is disposed to surround the display area of the first substrate.

11 . A method of manufacturing a liquid crystal display (LCD) device, the method comprising:
providing a first substrate and a second substrate, a display area and a bezel area surrounding the display area being defined in the first substrate and the second substrate; forming a thin film transistor (TFT) on the first substrate; forming a pixel electrode, electrically connected to the TFT, on the first substrate; forming an inner black matrix and an outer black matrix which are disposed in the bezel area of the second substrate face-bonded to the first substrate to be spaced apart from each other; and forming a liquid crystal layer disposed between the first substrate and the second substrate.

12 . The method of claim 11 , wherein the inner black matrix and the outer black matrix are independently formed to be spaced apart from each other with a certain gap therebetween.

13 . The method of claim 11 , wherein the inner black matrix and the outer black matrix are formed to surround the display area of the second substrate.

14 . The method of claim 11 , wherein the inner black matrix and the outer black matrix are simultaneously formed.

15 . The method of claim 11 , further comprising:
forming a ground line in the bezel area of the first substrate.

16 . The method of claim 15 , wherein the ground line of the first substrate is disposed to surround the display area of the first substrate.
