FPD spread widely instead of CRT. LCD has begun to spread early. This report shows the problems that give a defective product by attaching spacer in spraying device. During production, the spacer that attach to a nozzle becomes the droplet and falls on a glass panel. As a result, a defective product is gives by dropping spacer. In order to clarify the reason of a spacer attaching to a nozzle, a visualized model that is as large as an actual machine is prepared. Flow is visualized by LLS, and analyzed by PIV. From an analysis, a pattern of two jets is found. One is a pattern having an expanse at a certain angle. The other is a pattern that a vortex occurs in the upper part and that some vortex occurs in the lower part. Removing a vortex in the upper part is estimated to suppress the spacer of attaching.
