Abstract:
An object of the present invention is to provide a light source lens that makes it possible to improve unevenness in a luminance distribution, an illumination unit, and a display unit.
A light source lens (1) according to the present disclosure includes an incident surface on which light from a light-emitting device is incident, and an exit surface (20) that has a diffusing function at a center part (21) for light incident through the incident surface as well as a light-condensing function at at least a portion of an intermediate part (22) and a peripheral part (23) for the light incident through the incident surface.
