ABSTRACT:
A method of forming a spacer using an ink jet system and a method of fabricating a liquid crystal display panel using the same are to remarkably prevent generation of stains that result from a difference of spacer density between two adjacent heads in a border region of the heads, when a spacer is formed on the substrate surface by using an ink jet system, by forming a spacer pattern in a comb-teeth shape by providing a predetermined amount of overlapping between the two heads, and randomly and alternately spraying an organic material used solution for the spacer through nozzles of the heads. The method of forming a spacer using an ink jet system includes: providing a substrate that is divided into a plurality of pixel regions; spraying an organic material solution to first pixel regions of the substrate by using a first head; spraying an organic material solution to second pixel regions of the substrate by using a second head that overlaps with the first head; non-linearly spraying an organic material solution to third pixel regions of the substrate by using the first and second heads; and hardening the organic material solution sprayed to each of the pixel regions.
