Abstract:
A light source includes a plurality of light emitting elements one-dimensionally or two-dimensionally arranged, a plurality of wavelength conversion members, a plurality of first light diffusing members, a light transmitting member, a second light diffusing member, and a light shielding member. Each of the light emitting elements has a light emission surface and an electrode surface. Each of the wavelength conversion members is disposed on the light emission surface of a respective one of the light emitting elements. Each of the first light diffusing members is disposed on a respective one of the wavelength conversion members. The light transmitting member continuously covers the first light diffusing members. The second light diffusing member is disposed on the light transmitting member. The light shielding member covers lateral surfaces of the light emitting elements, lateral surfaces of the wavelength conversion members, and lateral surfaces of the first light diffusing members.
