Patent ID: 7522253

Claim:
A method of forming a liquid crystal layer on a substrate, comprising: preparing a liquid crystal material in a projecting portion; placing a resonating plate between a resonator and the projecting portion and outside of the projecting portion, wherein the resonator, the resonating plate and the projecting portion are arranged in a direction perpendicular to the substrate; applying an on voltage to the resonator during emitting of the liquid crystal material to generate a vibration with only a specific frequency by the resonator so as to apply a pressure to the projecting portion to emit the liquid crystal material from the projecting portion, wherein the generated vibration is transmitted from the resonator to the projecting portion through the resonating plate such that the resonating plate vibrates with the same specific frequency; moving the substrate in one direction; and depositing the liquid crystal material from the projecting portion uniformly onto the substrate during the moving of the substrate in the one direction, the substrate having a seal pattern and a black matrix at a region corresponding to the seal pattern, wherein the liquid crystal material is emitted from the projecting portion substantially in the same direction, which is perpendicular to the substrate, as the resonator vibrates.
