A light emitting device according to one embodiment includes a light emitting element that emits light having a wavelength of 250 nm to 500 nm and a fluorescent layer that is disposed on the light emitting element. The fluorescent layer includes a phosphor having a composition expressed by the following equation (1) and an average particle diameter of 12 μm or more. n (M 1−x1 Eu x1 ) 3−y Si 13−z Al 3+z O 2+u N 21−w (1)n n (In the equation (1), M is an element that is selected from IA group elements, IIA group elements, IIIA group elements, IIIB group elements except Al, rare-earth elements, and IVB group elements. x1, y, z, u, and w satisfy the following relationship. 0<x1≦1, −0.1≦y≦0.15, −1≦z≦1, −1<u−w≦1.5) |
