Abstract
The light source apparatus includes a light source, and a light guide plate configured to propagate a light beam from the light source in a specific direction. The light guide plate includes a splitter configured to split the light beam from the light source into a plurality of light beams, and to emit the plurality of light beams from the light guide plate. The splitter is configured such that a transmittance for a predetermined wavelength included in the light beam from the light source increases along the specific direction. A predetermined inequality is satisfied.
