An apparatus for forming an alignment layer of a liquid crystal display device includes: an alignment material dropping unit with a head having a plurality of holes for dropping an alignment material on the substrate; an alignment material supply unit to supply the alignment material to the alignment material dropping unit; a scan unit to survey alignment material dropping from the head; and a monitor to display an image base upon scan data from the scan unit so that the discharge state of the plurality of holes in the head can be checked.

Apparatus for forming alignment layer of liquid crystal display device

A method for forming an alignment layer of a liquid crystal display device includes 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 a plurality of heads, each of the heads having a plurality of holes arranged along a row at regularly-spaced interval distance d, and forming an alignment layer on the substrate to have a uniform thickness.

Apparatus for forming alignment film of liquid crystal display device and method for forming alignment film using the same

A method of forming an alignment layer for a liquid crystal display device including: attaching a transfer film on a printing roll, the transfer film including a convex portion having first-sized halftone dots and second-sized halftone dots; positioning a substrate on a printing table; providing aligning solution on an anilox roll using a doctor roll; and transferring the aligning solution on the anilox roll to the transfer film while moving the printing table and rotating the printing roll, and then coating the aligning solution on the substrate to thereby form an alignment layer on the substrate.

Method of forming alignment layer for liquid crystal display device

A method for forming an alignment layer of a liquid crystal display device includes providing a substrate having a plurality of unit panels formed thereon, loading the substrate onto a stage, selectively dropping an alignment material onto unit panel areas by using an alignment material dropping unit having a plurality of heads, each of the plurality of heads having a plurality of holes, and removing the alignment material remaining on a surface of the holes using an alignment material removal unit connected to the alignment material dropping unit.
