Abstract
The present invention relates to a composition for forming a fluorescent film for a display and a method of forming a fluorescent film for forming a display surface of a display unit. The composition for forming a fluorescent film for a display has an aqueous medium in which photosensitive resin having a styryl pyridium photosensitive group having an internal salt structure and a fluorescent material which easily reacts with acid are dispersed. The composition is applied to the display surface of a display unit so that a fluorescent layer is formed. Then, the fluorescent material layer is developed to form the fluorescent material layer into a predetermined pattern, and then the fluorescent material layer formed into the predetermined pattern is baked so that a fluorescent film is formed.
