COLOR-CONVERSION SUBSTRATE, LIGHTING DEVICE, AND COLOR DISPLAY DEVICE

摘要

A color-conversion substrate (101) provided with the following: a transparent substrate (1) that has a principal surface (1a); a plurality of phosphor layers (3) that are arranged on the aforementioned principal surface (1a) and each have side surfaces; a first low-refractive-index layer (9) that is interposed between the principal surface (1a) and the phosphor layers (3) and has a lower index of refraction than the phosphor layers (3); reflective films (6) that are formed on at least the sides of the phosphor layers (3) in order to reflect light exiting the side surfaces of said phosphor layers (3); and a second low-refractive-index layer (10) that has a lower index of refraction than the phosphor layers (3) and covers the parts of the phosphor layers (3) not covered by the reflective films (6) on the surfaces of said phosphor layers (3) on the opposite side from the transparent substrate (1).
