<P>PROBLEM TO BE SOLVED: To provide a light emitting device that achieves high color rendering properties using a light-emitting element and a phosphor. <P>SOLUTION: The light-emitting device includes: a light-emitting element 12 that emits light having a wavelength of 380-470 nm; a CASN first red phosphor that is disposed on the light-emitting element and is dispersed in a resin; a sialon second red phosphor that is disposed on the light-emitting element and is dispersed in a resin; and a sialon green phosphor that is disposed on the light-emitting element and is dispersed in a resin. The first red phosphor is disposed on the light-emitting element as a first red phosphor layer 22a, the second red phosphor is disposed on the light-emitting element as a second red phosphor layer 22b of the first red phosphor layer, and a green phosphor is disposed on the light-emitting element as a green phosphor layer 22 of the second red phosphor layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
