A light emitting device is provided in which fluorescence emitted from each phosphor in the color conversion plate containing multiple types of phosphors is hard to be absorbed by the other phosphor, and the light from the light emitting element is allowed to reach each of the phosphors efficiently. The color conversion plate has a sea-island structure including a sea region and an island region, and the island region contains the first phosphor and the sea region contains the second phosphor. The fluorescent wavelength of the first phosphor is longer than the fluorescent wavelength of the second phosphor. With the sea-island structure as described above, the contact area between the region containing the first phosphor and the region containing the second phosphor is reduced. The fluorescence of the second phosphor is hard to be absorbed by the first phosphor which has a longer wavelength.
