An illuminating unit includes: a light source section including a laser light source; a first uniformizing optical member on which light from the light source section is incident; and a second uniformizing optical member including a plurality of first unit cells and a plurality of second unit cells and on which light from the first uniformizing optical member is incident. The first unit cells are arranged on a light incidence surface of the second uniformizing optical member and each have an anisotropic shape with a major-axis direction as a first direction and a minor-axis direction as a second direction, and the second unit cells are arranged on a light emission surface of the second uniformizing optical member and each have a shape protruding along both the first direction and the second direction. |
