    Abstract: Disclosed is a light-emitting device (1) including a light-emitting element (2) emitting primary light, and a light converter (3) absorbing a part of the primary light emitted from the light-emitting element (2) and emitting secondary light having a longer wavelength than the primary light. The light converter (3) contains a green light-emitting phosphor (4) and a red light-emitting phosphor (5). The green light-emitting phosphor (4) is composed of at least one phosphor selected from a divalent europium-activated oxynitride phosphor substantially represented by the following formula: EuaSibAlcOdNe and a divalent europium-activated silicate phosphor substantially represented by the following formula: 2(Ba1-f-gMIfEug)O.SiO2, while the red light-emitting phosphor (5) is composed of at least one phosphor selected from tetravalent manganese-activated fluoro-tetravalent metalate phosphors substantially represented by the following formulae: MII2(MIII1-hMnh)F6 and/or MIV(MIII1-hMnh)F6. Consequently, the light-emitting device (1) has excellent color gamut (NTSC ratio).
