Spacer grain spreading manner to liquid crystal indicating element substrate and jig board and spreading device null for spreading

摘要

PROBLEM TO BE SOLVED: To eliminate an appearance defect and to prevent the degradation in yield by once arranging spacer particles on the prescribed part of a jig plate for spraying, then transferring the spacer particles in this arrangement to a liquid crystal display substrate. ;SOLUTION: The spacer particles 3 are sprayed atop the jig plate 1 for spraying from a spraying nozzle 4. Next, the jig plate 1 for spraying is inclined to apply vibration on the particles. At this time, the spacer particles 3 entering recessed parts 2 stay as they are in the recessed parts 2 and the spacer particles 3 are arranged in the recessed parts 2 in correspondence respectively thereto. Next, the liquid crystal display element substrate 7 provided with an oriented film 5 subjected to an orientation treatment is driven to align this liquid crystal display element substrate 7 and the jig plate 1 for spraying opposite to each other and, thereafter, the oriented film 5 is brought into contact with the spacer particles 3 on the jig plate 1 for spraying. Next, the liquid crystal display element substrate 7 is disposed on the lower side of the jig plate 1 for spraying. Finally, the jig plate 1 for spraying is parted from the liquid crystal display element substrate 7 to transfer the spacer particles 3 to the liquid crystal display element substrate 7 side.;COPYRIGHT: (C)1997,JPO
