FINE PARTICLE DISPERSION OF FLUORESCENT SUBSTANCE FOR THREE-DIMENSIONAL DISPLAY DEVICE, AND THREE-DIMENSIONAL DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an easily produceable fine particle dispersion of a fluorescent substance for a three-dimensional display device, using the fine particles of the fluorescent substance exhibiting upconversion fluorescence, and capable of being formed into the large size one; and to provide the three-dimensional display device. SOLUTION: The fine particle dispersion of the fluorescent substance is obtained by dispersing the fine particles of the fluorescent substance exhibiting the upconversion luminescence by being excited by the lights having two or more kinds of different wave lengths in a transparent liquid or a transparent resin.
