Abstract: Embodiments provide a phosphor including a silicate-based first phosphor emitting light having a yellow wavelength, a nitride-based second phosphor emitting light having a green wavelength, and a nitride-based third phosphor emitting light having a red wavelength. A full width at half maximum of the spectrum of mixed light emitted from the first phosphor to the third phosphor as the phosphors are excited by light having a blue wavelength is 110 nm or more.
