ABSTRACT:
A liquid crystal display device capable of reducing a disclination region generated when an alignment layer is not normally rubbed due to physical interference between a pattern spacer formed on a substrate and fibers of a rubbing cloth in a rubbing process and a rubbing and fabricating method thereof are disclosed. The liquid crystal display device includes a liquid crystal panel having two bonded substrates with a liquid crystal layer interposed therebetween, alignment layers formed on the two substrates to align liquid crystal molecules in a predetermined direction, and a pattern spacer formed on any one substrate to maintain a distance between the substrates. The alignment layers are rubbed by a rubbing cloth having fibers inclined in a left or right direction with respect to a perpendicular direction of a rotation shaft of a rubbing roll, and the pattern spacer has an inclined surface parallel to the fibers.
