Abstract
A method and an equipment in which a comparatively thick film such as the barrier rib of a plasma display panel is formed by one time of coating process. According to the nozzle coating equipment (10), a coating line (21A) is formed in such a way that, while a coating solution is being discharged from the tip of a nozzle (20) which is provided at the lower end of a liquid vessel (18) filled with the coating solution, the liquid vessel (18) carrying the nozzle (20) is driven in an X-direction relatively to a glass plate (16). Subsequently, the liquid vessel (18) is shifted in a Y-direction to the amount of a pitch P which is smaller than the width of each coating line, whereupon the next coating line (21B) is formed. Thus, a coated surface (22) is formed on the glass plate (16) in such a manner that the adjacent coating lines overlap each other in the widthwise direction thereof in succession.
