FLUORESCENT CONVERTING FILM, RESIN COMPOSITION FOR FLUORESCENT CONVERTING FILM AND ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a technique for improving continuous driving durability while keeping high light emitting intensity. SOLUTION: At least one or more kinds of fluorescent coloring matters and an additive for capturing energy from the fluorescent coloring matters are contained, and when a minimum exciting triplet energy level of the additive is '3Eq', and a minimum exciting triplet energy level of a main light emitting fluorescent coloring matter having a fluorescent peak wave length of the longest wave length among the fluorescent coloring matters is '3Ed', the relationship of '3Eq<3Ed' is satisfied.
