LIGHT-EMITTING SUBSTRATE, MANUFACTURING METHOD THEREOF, AND ELECTRON-BEAM EXCITATION IMAGE DISPLAY APPARATUS USING LIGHT-EMITTING SUBSTRATE

摘要

A phosphor having the lowest E/L ratio of the luminance (L) to the luminous efficiency (E) of each phosphor for obtaining a target chromaticity of white using a plurality of phosphors which emit different colors on a light-emitting substrate is selected, and the light reflectance of the portion of the metal back layer formed on this phosphor is set to be higher than the portion formed on the other phosphors.
