Abstract

A liquid crystal display device includes: a first substrate having a plurality of gate lines and a plurality of data lines crossing each other; a second substrate facing the first substrate; a first pattern spacer having an inverse tapered shape on an inner surface of the first substrate; a second pattern spacer having an inverse tapered shape on an inner surface of the second substrate; a seal pattern on a peripheral edge of the first and second substrates; and a liquid crystal layer between the first and second substrates.

Claims (30)

1. A liquid crystal display device comprising:

a first substrate having a plurality of gate lines and a plurality of data lines crossing each other;

a second substrate facing the first substrate;

a plurality of first pattern spacers having an inverse tapered shape on an inner surface of the first substrate;

a plurality of second pattern spacers having an inverse tapered shape on an inner surface of the second substrate;

a seal pattern on a peripheral edge of the first and second substrates; and

a liquid crystal layer interposed between the first and second substrates,

wherein the first and second pattern spacers are alternately disposed each other.

2. The liquid crystal display device according to claim 1 , wherein the first and second pattern spacers are made of an organic insulation material.

3. The liquid crystal display device according to claim 1 , wherein the first and second pattern spacers are made of a negative photoresist material.

4. The liquid crystal display device according to claim 1 , wherein the first and second pattern spacers are made of Novalac photoresist resin.

5. The liquid crystal display device according to claim 1 , wherein the first and second pattern spacers are interlocked with each other.

6. The liquid crystal display device according to claim 1 , wherein the first pattern spacers are formed on a region of the first substrate where one of the thin film transistor, a capacitor, and the pluralities of gate and data lines are formed.

7. The liquid crystal display device according to claim 1 , wherein the second pattern spacers are formed on a region of the second substrate where a black matrix layer of the second substrate is formed.

8. The liquid crystal display device according to claim 7 , wherein more second pattern spacers are formed on the second substrate than first pattern spacers formed on the first substrate.

9. A liquid crystal display device comprising:

a first substrate having a plurality of gate lines and a plurality of data lines crossing each other;

a second substrate facing the first substrate;

a plurality of first pattern spacers having an inverse tapered shape on an inner surface of the first substrate;

a plurality of second pattern spacers having an inverse tapered shape on an inner surface of the second substrate;

a seal pattern a peripheral edge of the first and second substrates; and

a liquid crystal layer between the first and second substrates,

wherein the first and second pattern spacers are interleaved.

10. The liquid crystal display device according to claim 9 , wherein the first and second pattern spacers are made of an organic insulation material.

11. The liquid crystal display device according to claim 9 , wherein the first and second pattern spacers are made of a negative photoresist material.

12. The liquid crystal display device according to claim 9 , wherein the first and second pattern spacers are made of a Novalac photoresist resin.

13. The liquid crystal display device according to claim 9 , wherein the first and second pattern spacers are interlocked with each other.

14. The liquid crystal display device according to claim 9 , wherein the first pattern spacers are formed on a region of the first substrate where one of the thin film transistor, a capacitor, and the pluralities of gate and data lines are formed.

15. The liquid crystal display device according to claim 9 , wherein the second pattern spacers are formed on a region of the second substrate where a black matrix layer of the second substrate is formed.

16. The liquid crystal display device according to claim 14 , wherein more second pattern spacers are formed on the second substrate than first pattern spacers formed on the first substrate.
