Patent ID: 7403250

Claim:
A method for forming an alignment layer of a liquid crystal display device, comprising: providing a substrate having a plurality of unit panels formed thereon; loading the substrate onto a stage; selectively dropping an alignment material onto a first one of the unit panel regions by an alignment material dropping unit having at least one head, each head having a plurality of holes; and forming an alignment layer on the substrate to have a uniform thickness, wherein the selective dropping of the alignment material onto the substrate comprises: positioning the alignment material dropping unit at a first side of the stage; driving the alignment material dropping unit from the first side to a second side of the stage to drop the alignment material through holes along a plurality of first dropping paths along a first dropping direction; shifting the alignment material dropping unit by a predetermined distance along a direction substantially perpendicular to the first dropping direction; and driving the alignment material dropping unit from the second side to the first side of the stage to drop the alignment material through holes along a plurality of second dropping paths, wherein the shift distance of the alignment material dropping unit is smaller than a distance between the holes, such that the second dropping paths are disposed in a region at a separation distance from the first dropping paths between the first dropping paths, whereby the alignment materials in the first and second dropping paths spread after dropping to contact each other.
