    摘要： A light-emitting device includes a light-emitting element; one or more silver-based members having silver on their surfaces; and a resin layer including a first resin layer covering at least one of the silver-based members, and a second resin layer placed directly on the first resin layer. The light-emitting element is covered with the first resin layer or both the first resin layer and the second resin layer, at least one of the first resin layer and the second resin layer contains an inorganic adsorbent which chemically adsorbs a sulfide, the second resin layer contains a sulfide-based phosphor, and a ratio of a thickness of the first resin layer with respect to a total thickness of the first resin layer and the second resin layers is 50% or more.

    摘要： 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.
