Patent ID: 7491273

Claim:
An apparatus for forming an alignment layer of a liquid crystal display device comprising: an alignment material dropping unit with a plurality of heads having a plurality of holes for dropping an alignment material on a substrate, a plurality of heads being attachable each other; an alignment material supply unit to supply the alignment material to the alignment material dropping unit; a plurality of scan units structurally coupled to each head of the alignment material dropping unit to survey alignment material dropping from the heads, each scan unit scanning the alignment material dropped from the corresponding heads; and a monitor to display a plurality of images based upon scan data from the scan units so that a discharge state of the plurality of holes in each head can be checked, wherein the number of the heads to be attached each other is dependent upon the size of the substrate and the size of the holes and the distance between the holes are dependent upon the thickness of an alignment layer, wherein a plurality of holes in a plurality of heads are disposed along the first side of the substrate in a line and the alignment material is dropped onto the substrate along the second side of the substrate perpendicular to the first side.
