Light emitting device

A device comprising:

• a light emitting device comprising:
• a light emitting element adapted to emit a blue light,
• a sealing resin covering the light emitting element, and
• a sulfide phosphor-containing layer disposed separate from the sealing resin;
• and
• a light guide plate,
• wherein the sealing resin includes one or both of:
• (i) a KSF phosphor, wherein the KSF phosphor is a compound having the chemical formula:
• A2 [M1−aMn4+aF6]
• where A is at least one selected from the group consisting of K+, Li+, Na+, Rb+, Cs+and NH4+,
• M is at least one element selected from the group consisting of Group 4 elements and Group 14 elements, and
• 0<a<0.2;
• and
• the KSF phosphor is adapted to absorb at least a portion of the blue light emitted from the light emitting element to emit red light, and
• (ii) a MGF phosphor, wherein the MGF phosphor is a compound having the chemical formula:
• (x−a)MgO.(a/2)Sc2O3.yMgF2.cCaF2.(1−b)GeO2.(b/2)Mt2O3:zMn4+
• where 2.0≦x≦4.0,
• 0<y<1.5,
• 0<z<0.05,
• 0≦a<0.5,
• 0<b<0.5,
• 0≦c<1.5
• y+c <1.5, and
• Mt is at least one element selected from Al, Ga and In, and
• the MGF phosphor is adapted to absorb at least a portion of the blue light emitted from the light emitting element to emit red light;
• and
• wherein the sulfide phosphor-containing layer includes a sulfide phosphor having the chemical formula:
• M1Ga2S4:Eu
• which is a thiogallate phsophor activated with Eu, where M1 is at least one selected from Mg, Ca, Sr and Ba, and the sulfide phosphor is adapted to absorb at least a portion of the blue light emitted from the light emitting element to emit green light,
• wherein the sealing resin is disposed facing a lateral surface of the light guide plate, and the sulfide phosphor-containing layer is disposed facing an upper surface of the light guide plate.
