DEVICE AND METHOD FOR FORMING PHOSPHOR FILM FOR PLASMA DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To precisely form a phosphor film on a substrate without improper application and mixed color. SOLUTION: In this method for forming a phosphor film for a plasma display panel, phosphor liquid 3 discharged from multiple nozzles 2 are applied to a plurality of pieces of grooves 4 provided in parallel on a substrate 5 while the nozzles 2 travel relatively to the substrate 5 in the lengthwise direction of the grooves 4, and the phosphor film is formed on the substrate 5. The application work of the phosphor liquid 3 is conducted while placing neighboring discharge openings 2a of the nozzles 2 in different positions each other in the relative travel direction of the nozzles 2a.
