Embodiments of the present invention provide a bluish green phosphor represented by Formula 1 below. In particular, the bluish green phosphor and a light emitting device package including the same may have improved luminescence characteristics and properties due to influence of cations and anions included in a composition formula: n n [Formula 1] A a B b O c N d C e D f E g :RE h n nwherein A is at least one selected from the group consisting of Be, Mg, Ca, Sr, Ba and Ra elements, B is at least one selected from the group consisting of Si, Ge and Sn elements, C is any one of C, Cl, F and Br elements, D is one element or a mixture type of two or more elements selected from Li, Na and K, E is at least one selected from the group consisting of P, As, Bi, Sc, Y and Lu, RE is at least one selected from the group consisting of Eu, Ce, Sm, Er, Yb, Dy, Gd, Tm, Lu, Pr, Nd, Pm and Ho, 0<a≤15, 0<b≤15, 0<c≤15, 0<d≤20, 0<e≤10, 0<f≤6, 0<g≤6, and 0<h≤10. |
