Claim 2:
3. The white light emitting device according to claim 1,
wherein when n is a total number of the plurality of first light-emitting units and m is a total number of the plurality of second light-emitting units,
an emission chromaticity of each of the plurality of first light-emitting units at the time of application of the first current to the plurality of first light-emitting units is represented by CIE coordinates (Cx11i, Cy11i) (1≤i≤n), and
an emission chromaticity of each of the plurality of second light-emitting units at the time of application of the first current to the plurality of second light-emitting units is represented by CIE coordinates (Cx21i, Cy21i) (1≤i≤m),
all of the CIE coordinates (Cx11i, Cy11i) are inside a region represented by |Cx11−Cx11i|<0.0055 and |Cy11−Cy11i|<0.0074, and
all of the CIE coordinates (Cx21i, Cy21i) are inside a region represented by |Cx21−Cx21i|<0.0055 and |Cy21−Cy21i|<0.0074.
