Abstract
The present invention aims to provide a luminescent display system capable of safely and easily displaying information at a predetermined luminance over a wide area, and a head-up display including the luminescent display system. Provided is a luminescent display system including: a luminescent resin film containing a thermoplastic resin and a luminescent material; and two or more light sources each configured to emit a light beam of excitation wavelength for the luminescent material, the luminescent resin film and two or more light sources being placed such that the light beams emitted from the light sources at least partly overlap on the luminescent resin film.
