Abstract
A light source includes light emission units and a light shielding member. At least one of the light emission units includes a light emitting element, a wavelength conversion member, and a light transmissive member. The light transmissive member includes a first region positioned above the light emitting element and a second region positioned outward from the first region. The second region has a thickness smaller than a thickness of the first region. The wavelength conversion member is larger than the light emission face of the light emitting element in a top view. The light shielding member is continuously disposed between adjacent ones of the light emission units and covers a lateral face of the light emitting element and a lateral face of the wavelength conversion member. A lateral face of the light transmissive member in the light emission unit is at least partially exposed from the light shielding member.
