Abstract: In order to suppress the chromaticity shift and corrosion associated with the deterioration of a sulfide phosphor particle, this phosphor sheet is produced using a phosphor particle-containing resin composition which comprises: covered phosphor particles; polymerizable compound; and a polymerization initiator. The covered phosphor particles are obtained by covering phosphor particles with silicon dioxide films, wherein among the phosphor particles, at least sulfide phosphor particles are covered with silicon dioxide films that contain a metal oxide powder. Thus, the phosphor sheet can be inhibited from emitting a sulfur-based gas, and exhibits a minimized chromaticity shift, even when the phosphor sheet is present in such a manner that the edge of the phosphor layer of the sheet is in an exposed state.
