Abstract
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.

An illuminating unit, comprising:
- 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 being arranged on a light incidence surface of the second uniformizing optical member and each having 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 being arranged on a light emission surface of the second uniformizing optical member and each having a shape protruding along both the first direction and the second direction.
A display, comprising:
- an illuminating unit emitting illumination light;
- and
- a light modulation device modulating the illumination light based on an image signal,
- the illuminating unit including
- 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 being arranged on a light incidence surface of the second uniformizing optical member and each having 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 being arranged on a light emission surface of the second uniformizing optical member and each having a shape protruding along both the first direction and the second direction.
