The present invention suppresses chromaticity deviation or corrosion accompanying deterioration of a sulfide phosphor. The present invention uses a phosphor-containing resin composition containing a phosphor coated with a phosphor dioxide film, a polymerizable compound, and a polymerization initiator, and at least a sulfide in the phosphor The body 2 is covered with a ruthenium dioxide film 4 containing a metal oxide powder 3. Thereby, even if the phosphor sheet is exposed at the end of the phosphor layer, the release of the sulfur-based gas can be prevented, and the chromaticity deviation can be reduced. |
