Printing device system, patterning method using the same, and method of fabricating liquid crystal display device using the same

1 . A printing device system comprising:

a printing plate including protruding and groove patterns; and

hydrophobic layers in the groove patterns.

2 . The system of claim 1 , wherein the protruding patterns of the printing plate have the hydrophilic properties.

3 . The system of claim 1 , wherein the hydrophobic layers have a surface energy which is smaller than that of the protruding patterns of the printing plate.

4 . The system of claim 1 , wherein the hydrophobic layers are formed of metal.

5 . The system of claim 1 , further comprising:

a printing roll to transcribe some of a pattern material on the printing plate and to transcribe the other of the pattern material on a substrate; and

a printing nozzle to supply the pattern material to the printing roll.

6 . The system of claim 5 , wherein the printing roll has a blanket adhered to the outer surface of the printing roll.

7 . The system of claim 1 , further comprising a cleaning device to clean the printing plate.

8 . The system of claim 1 , wherein the hydrophobic layers are formed by photolithograph process comprising steps of:

forming the groove patterns in a substrate for the printing plate;

forming a hydrophobic material on the substrate including the groove patterns;

forming a photoresist pattern on the hydrophobic material above the groove patterns; and

etching the hydrophobic material using the photoresist pattern as a mask to form the hydrophobic layers on the groove patterns.

9 . A patterning method comprising:

coating a blanket adhered to an outer surface of a printing roll with a pattern material;

rolling the printing roll on a printing plate including protruding and groove patterns, the groove patterns provided with hydrophobic layers, to transcribe the pattern material on the protruding patterns of the printing plate, and to form a predetermined pattern on the printing roll by the remaining pattern material; and

rolling the printing material on a substrate to transcribe the predetermined pattern on the substrate.

10 . The patterning method of claim 9 , wherein coating the printing roll with the pattern material is performed with a printing nozzle.

11 . The pattering method of claim 9 , wherein the protruding patterns of the printing plate have the hydrophilic properties.

12 . The patterning method of claim 9 , wherein the hydrophobic layers have a surface energy which is lower than that of the protruding patterns of the printing plate.

13 . The patterning method of claim 9 , wherein the hydrophobic layers are formed of metal.

14 . The patterning method of claim 9 , further comprising cleaning the printing plate.

15 . A method of fabricating an LCD device comprising:

preparing first and second substrates; and

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

wherein preparing the first substrate includes forming a pattern on the first substrate, and forming the pattern on the substrate is performed by the patterning method of any one of claims 9 to 14 .

16 . The method of claim 15 , wherein the pattern corresponds to a black matrix layer or a color filter layer.

17 . The method of claim 15 , wherein forming the liquid crystal layer comprises:

forming a sealant including an inlet in any one of the first and second substrates;

bonding the first and second substrates to each other; and

injecting liquid crystal into the space between the first and second substrates through the inlet.

18 . The method of claim 15 , wherein forming the liquid crystal layer comprises:

forming a sealant having no inlet in any one of the first and second substrates;

dispensing liquid crystal on any one of the first and second substrates; and

bonding the first and second substrates to each other.
