摘要： An illuminating device capable of improving display luminance while decreasing light leakage in a range with a large view angle and a display unit are provided. In a light modulation device bonded to a light guide plate, a light modulation layer containing a bulk and microparticles is provided. Both the bulk and the microparticles have optical anisotropy, and each response speed to an electric field is different from each other. Thereby, by controlling the electric field, each optical axis orientation of the bulk and the microparticles is able to correspond with each other, or is able to be different from each other.

摘要： An illumination device capable of suppressing formation of a double image in three-dimensional display, and a display unit including the illumination device are provided. In a light modulation device bonded to a light guide plate, a scattering region that scatters light propagating within the light guide plate, and a transmissive region that allows light propagating within the light guide plate to pass therethrough are formed through control of an electric field. The scattering region scatters light to generate linear illumination light. A reflector is provided directly below the light modulation device. The reflector reflects light, which is part of the scattered light generated in the scattering region and is emitted to a reflector side, to generate reflected light to be focused directly below the scattering region.

摘要： A light modulation layer disposed between a first transparent substrate and a second transparent substrate generates a plurality of first strip-like illumination light beams extending in a direction intersecting with a first end surface of the first or second transparent substrate at a first angle with use of light from a light source, when an electric field for a first mode is applied from an electrode to the light modulation layer. The light modulation layer generates a plurality of second strip-like illumination light beams extending in a direction intersecting with the first end surface at an angle different from the first angle or a direction parallel to the first end surface with use of light from the light source, when an electric field for a second mode is applied from the electrode to the light modulation layer.
