    摘要： There are provided an illumination unit and a display which are capable of further uniformizing chromaticity of illumination light in a plane while suppressing a reduction in light extraction efficiency. A light modulation device bonded to a light guide plate includes a light modulation layer exhibiting a scattering property or transparency with respect to light propagating through the light guide plate. The light modulation layer is sandwiched between a pair of transparent substrates. While alignment films controlling alignment of the light modulation layer are disposed on surfaces of the transparent substrates, an electrode generating an electric field which changes the alignment of the light modulation layer is disposed on only the surface of the transparent substrate.

    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.
