Abstract
A light source includes first and second light emission units and a light shielding member. The light emission units each includes a light emitting element having a light emission face, a wavelength conversion member disposed on the light emission face, and a light transmissive member disposed on the wavelength conversion member. The light shielding member covers a lateral face of the light emitting element and a lateral face of the wavelength conversion member. The lateral face of the light transmissive member is at least partially exposed from the light shielding member. The second light emission unit is more distant from a center of a predetermined region than the first light emission unit. The light emission face of the light emitting element in the second light emission unit is larger than the light emission face of the light emitting element in the first light emission unit.
