Abstract
A light emitting device includes a first light emitting element that outputs a first emitted light having a first peak wavelength, a second light emitting element that outputs a second emitted light having a second peak wavelength, and a phosphor layer including a plurality of phosphors, which is disposed on the first and second light emitting elements. The phosphor layer receives the first and second emitted light and outputs a plurality of emitted light based on the plurality of phosphors so as to form a first synthesized emission spectrum. The second light emitting element includes an emission spectrum to reduce a depth of a deepest dip of at least one dip in a second synthesized emission spectrum that is formed by removing an emission spectrum of the second emitted light from the first synthesized emission spectrum.
