A light source device comprises a plurality of kinds of light sources having different directivity characteristics and including a first light source and a second light source having a directivity characteristic wider than a directivity characteristic of the first light source; and a diffusing structure section for radiating light emitted by the first light source after diffusing the light, wherein a position of a center of a first brightness distribution of light radiated from the diffusing structure section in a case when the first light source emits light is a position corresponding to a position of a center of a second brightness distribution in a case when the second light source emits light. |
