PROBLEM TO BE SOLVED: To provide a light-emitting composition, light-source device and displaying device having a phosphor aiming at both of the avoidance of light-emitting wave length band becoming short wave and suppression of the color unevenness. SOLUTION: This light-emitting composition containing the phosphor having the same crystal structure with CaAlSiN<SB>3</SB>is provided by having a constitution containing carbon by at least≥0.05 wt.% ratio.
