Patent ID: 8128995

Claim:
A method of fabricating a liquid crystal display panel containing a substrate, the method comprising: inhaling gaseous matter on a surface of the substrate using an intake pipe of a slit nozzle, wherein the slit nozzle includes a first injection pipe for injecting a photo resist liquid, a second injection pipe for spraying a gas and the intake pipe for intaking the gaseous matter, is spaced from the substrate, wherein the intake pipe, the first injection pipe and the second injection pipe are sequentially arranged along a moving direction of the slit nozzle; applying the photo resist liquid to the surface of the substrate through the first injection pipe of the slit nozzle while the slit nozzle is moving along a longitudinal direction of the substrate; and spraying the gas on the photo resist liquid applied to surface of the substrate through the second injection pipe of the slit nozzle perpendicular to the surface of the substrate, wherein the gas from the second injection pipe of the slit nozzle is sprayed on only the photo resist liquid applied on the surface of the substrate in a direction perpendicular to the surface of the substrate to prevent bubbles from being generated on the photo resist liquid applied to surface of the substrate, and wherein the slit nozzle further comprises a third injection nozzle disposed adjacent to the second injection nozzle and spraying a gas onto the photo resist liquid applied to the surface of the substrate in an oblique direction with respect to the substrate.
