Pattern mask, liquid crystal injection process, and method of fabricating LCD device using the same

1. A liquid crystal injection process for fabricating a liquid crystal display (LCD) device, comprising:

attaching a liquid crystal material to a pattern mask to form a liquid crystal film; and

printing the liquid crystal film on a substrate for the LCD device by pressing the pattern mask to the substrate.

2. The process according to claim 1 , wherein the attaching a liquid crystal material to a pattern mask comprises disposing the pattern mask to correspond to a liquid crystal tray having the liquid crystal material therein; and dipping the pattern mask into the liquid crystal tray.

3. The process according to claim 1 , wherein the printing the liquid crystal film on a substrate comprises aligning the pattern mask having the liquid crystal film thereon with the substrate; and then pressing the pattern mask to the substrate.

4. The process according to claim 1 , wherein the pattern mask has a mesh shape.

5. The process according to claim 4 , wherein the pattern mask comprises a plurality of prominences arranged in a lattice form.

6. The process according to claim 5 , wherein the liquid crystal material is attached inside the prominences of the pattern mask.

7. The process according to claim 1 , wherein the substrate has a seal pattern surrounding a display region thereon.

8. The process according to claim 7 , wherein the seal pattern has a closed shape.

9. The process according to claim 8 , wherein the liquid crystal film is printed in the seal pattern.

10. The process according to claim 9 , wherein the liquid crystal film printed on the substrate spreads toward the seal pattern.

11. The process according to claim 1 , further comprising removing bubbles in the liquid crystal material before attaching the liquid crystal material to the pattern mask.

12. A method of fabricating a liquid crystal display (LCD) device, comprising:

attaching a liquid crystal material to a pattern mask to form a liquid crystal film;

printing the liquid crystal film on a first substrate by pressing the pattern mask to the first substrate; and

attaching the first substrate having the liquid crystal film thereon with a second substrate.

13. The method according to claim 12 , wherein the attaching a liquid crystal material to a pattern mask comprises disposing the pattern mask to a liquid crystal tray having the liquid crystal material; and dipping the pattern mask into the liquid crystal tray.

14. The method according to claim 12 , wherein the printing the liquid crystal film on a first substrate comprises aligning the pattern mask having the liquid crystal film thereon with the first substrate; and then pressing the pattern mask to the first substrate.

15. The method according to claim 12 , wherein the pattern mask has a mesh shape.

16. The method according to claim 15 , wherein the pattern mask comprises a plurality of prominences arranged in a lattice form.

17. The method according to claim 16 , wherein the liquid crystal material is attached inside the prominences of the pattern mask.

18. The method according to claim 12 , wherein the first substrate has a seal pattern surrounding a display region thereon.

19. The method according to claim 18 , wherein the seal pattern comprises a closed shape.

20. The method according to claim 19 , wherein the liquid crystal film is printed in the seal pattern.

21. The method according to claim 20 , wherein the liquid crystal film printed on the first substrate spreads toward the seal pattern.

22. The method according to claim 12 , further comprising removing bubbles in the liquid crystal material before attaching the liquid crystal material to the pattern mask.

23. The method according to claim 12 , wherein the attaching the first substrate having the liquid crystal film thereon onto the second substrate comprises aligning the first substrate with the second substrate; and attaching the first substrate and the second substrate.
