Abstract
A spacer spraying device for spraying a powdery spacer onto, e.g., a substrate for an LCD (Liquid Crystal Display) is disclosed. When the device sprays the spacer onto the top of the substrate in a spray chamber, it prevents the spacer from depositing on the inner side walls and top wall of the chamber and dropping in the form of cohered masses onto the substrate.
