A method for forming an alignment layer of a liquid crystal display device comprising:
- providing a substrate with a unit panel area;
- loading the substrate on a stage;
- selectively dropping an alignment material onto the unit panel area through an alignment material dropping unit having a head that has a plurality of holes through which the alignment material is dropped;
- and
- removing alignment material remaining about the holes of the alignment material dropping unit by an alignment material removing unit which scrapes the surface of the alignment material dropping unit having the holes therein.
An apparatus for forming an alignment layer of a liquid crystal display device comprising:
- a stage to hold a substrate loaded thereon;
- an alignment material dropping unit having a head with a plurality of holes to drop an alignment material on the substrate;
- an alignment material supply unit to supply the alignment material to the alignment material dropping unit;
- and
- an alignment material removing unit to remove alignment material remaining about the holes.
An apparatus for forming an alignment layer of a liquid crystal display device comprising:
- a stage for holding a substrate;
- an alignment material dropping means having holes for dropping an alignment material on the substrate;
- an alignment material supply means for supplying the alignment material to the alignment material dropping unit;
- and
