Abstract: A light emitting device can make it hard for fluorescence emitted from each phosphor in a color conversion plate to be absorbed by other phosphor. The color conversion plate can include multiple types of phosphors, and the light from a light emitting element can be allowed to reach each of the phosphors efficiently.

A region where the first regions and the second regions are excluded, as viewed from a location on top of the conversion plate, contains no phosphor.
