A light source unit includes a plate including a front surface and a rear surface opposite to the front surface, a light scattering section on the front surface of the plate, a light controlling section on the light scattering section and including a plurality of quantum dots, a light source on the rear surface of the plate and including a light emitting element which generates light, a light emitting surface from which the light is emitted, and a plurality of lead frames connected to the light emitting element. The light source provides light from the rear surface of the plate toward the light controlling section. The light emitting surface of the light source is in contact with the rear surface of the plate.
