Abstract
The present invention provides a light source unit capable of displaying an image of a desired color without causing color unevenness when mounted on a display. A light source unit including: a light source; a color conversion member that converts incident light incident from the light source into light having a longer wavelength than the incident light does; and a reflective film that is present between the light source and the color conversion member, transmits light incident from the light source, and reflects light exited from the color conversion member, wherein in the reflective film, the scattering angle (R2−R1) on at least one film surface is 5° or more, where the scattering angle is obtained from angles R1 and R2 (R1<R2) at which the transmitted light intensity is Tmax(0)/100 relative to the maximum transmitted light intensity of halogen light incident perpendicularly to the film surface of Tmax(0).
