An illuminating apparatus includes: a light source, and a lens sheet arranged on an optical axis of the light source on which a plurality of prisms arranged in concentric circles centered on the optical axis of the light source are formed. A light diffusing part including a plurality of hemispherical light scattering elements is provided on the lens sheet, the light diffusing part includes light scattering elements whose shape is distorted due to influence of light scattering elements that are adjacent in at least one direction, and the plurality of light scattering elements is arranged in concentric circles centered on the optical axis of the light source. |
