Abstract
The present invention aims to provide a luminescent curved glass which, despite being curved with a small radius of curvature, can provide a clear display on its entire surface when irradiated with light, and curved digital signage including the luminescent curved glass. Provided is a luminescent curved glass including a laminate including a transparent plate having a radius of curvature of 3,000 mm or lower and a luminescent sheet, the luminescent sheet containing a thermoplastic resin and a luminescent material that emits visible light having a wavelength of 380 to 750 nm under excitation light.
