A slit coater including buffer members having elasticity and installed at both sides of a slit nozzle unit, compensating for a height difference between both sides, preventing breakdown due to excessive stress generated by the height, and reducing set-up time. The slit coater includes: a table on which an object to be processed is mounted; a slit nozzle unit formed above the table for applying coating solution onto the object; a driving unit moving the slit nozzle unit in a predetermined direction; and buffer members having elasticity installed at both sides of the slit nozzle unit.

What is claimed is: 1. A method for fabricating an LCD device comprising: applying a coating solution onto a surface of an LCD substrate using a slit nozzle unit; and while applying the coating solution, freely adjusting a height difference between both sides of the slit nozzle unit in a vertical (z-axial) direction using elastic buffer members coupled between the side of the slit nozzle unit and a driving unit having a pair of z-axial driving apparatuses installed at both ends of the slit nozzle unit, wherein during a vertical driving of the pair of z-axial driving apparatuses, the elastic buffer members compensate for the height difference. 2. The method of claim 1, wherein freely adjusting the height difference between both sides of the slit nozzle unit comprises using elastic buffer members coupled between the side of the slit nozzle unit and the driving unit configured to move the slit nozzle unit in a predetermined direction. 3. The method of claim 1 further comprising mounting the LCD substrate on a table in spaced relation with the slit nozzle unit. 4. The method of claim 1, wherein using the elastic buffer members comprises elastically buffering the vertical movement of the slit nozzle unit. 5. The method of claim 1, wherein applying a coating solution comprises applying one of a photosensitive solution, a development solution, or a color filter. 6. The method of claim 1, wherein using a slit nozzle unit comprises providing a nozzle having a long slit and a head to which the nozzle is mounted, wherein the length of the slit is longer than its width. 7. The method of claim 1, wherein using the buffer members comprises providing the buffer members with a first coupling portion coupled to one side of the slit nozzle unit, a second coupling portion coupled to a predetermined region of the driving unit, and a buffer portion formed between the first coupling portion and the second coupling portion. 8. The method of claim 7, wherein providing the buffer members with the first and second coupling portions comprises providing at least one bend between the first and second coupling portions. 9. The method of claim 7, wherein providing the buffer members with the first and second coupling portions comprises providing at least one of an S shape, a reversed S shape, or a combination thereof by creating a first bend at the first coupling portion and a second bend toward the second coupling portion. 10. The method of claim 1, further comprising providing at least one vent formed at an upper portion of the nozzle and configured to discharge air.
