Abstract
A light source unit includes: a light emitting body; and a color conversion film including an organic luminescent material configured to convert at least a part of incident light incident from the light emitting body into light having a wavelength longer than a wavelength of the incident light. The light emitting body includes a light source, and a layer including a green phosphor and formed on the light source. The organic luminescent material has a light emission wavelength peak in a wavelength region of 580 nm or longer and 750 nm or shorter.
