Abstract:
1. A light source apparatus, comprising a plurality of light emitting element modules provided therein, in which a plurality of light source sections each comprising a light emitting element are mounted on a substrate, for all of the plurality of light source sections simultaneously emitting light planarly, the plurality of light source sections comprising a light source section with a narrow light distribution property having a brightness peak that is high and a light source section with a broad light distribution property having the brightness peak that is low, wherein when a plurality of the light source sections are arranged in a matrix in a row direction and a column direction in a plane view, the light source section with a narrow light distribution property having a brightness peak that is high and the light source section with a broad light distribution property having the brightness peak that is low are being alternately arranged for only each row or only each column, wherein the light source section comprises a reflecting material provided on a substrate region around the light emitting element, in addition to the light emitting element, and the light source section with high contrast and the light source section with low contrast are formed by the difference in a reflection rate of the reflecting material.
