Claim Text:
1. A light emitting device comprising: at least one light emitting element emitting a light comprising a peak emission wavelength in a near-ultraviolet to blue region; and a phosphor layer comprising a green phosphor excited by a primary light emitted from the light emitting element and emitting a light comprising a peak emission wavelength in a green region, a first red phosphor excited by the primary light and emitting a light comprising a peak emission wavelength in a red region, and a second red phosphor exited by the primary light and emitting a light comprising a peak emission wavelength different from that of the first red phosphor in the red region, wherein the peak emission wavelength of the green phosphor falls within a wavelength range of 510 nm or more and 550 nm or less, the green phosphor comprising a half-value width of 95 nm or more in emission spectrum, the peak emission wavelength of the first red phosphor falls within a wavelength range of 610 nm or more and less than 625 nm, the first red phosphor comprising a half-value width of 85 to 110 nm in emission spectrum, and the peak emission wavelength of the second red phosphor falls within a wavelength range of 625 nm or more and 670 nm or less, the second red phoshor comprising a half-value width of 85 to 110 nm in emission spectrum.
