    摘要： Provided is a display unit capable of improving both display luminance and display quality in three-dimensional display. A light modulation layer containing a bulk and microparticles is provided in a light modulation device (30) that is bonded to a light guide plate (10). The bulk and the microparticle each have optical anisotropy, and have respective response speeds to the electric field, that are different from each other. When the electric field is applied to the light modulation layer, an optical axis (AX1) of the bulk and an optical axis (AX2) of the microparticle are orthogonal to each other in a light modulation cell (30-1, 30-2). At this time, the optical axis (AX1) of the bulk is parallel to a transmission axis (AX10) of a polarization plate (210B) on a backlight side.

    摘要： A display unit is provided including: a display panel having a plurality of pixels two-dimensionally arranged; a first polarization plate and a second polarization plate that face each other with the display panel in between; and an illumination device configured to illuminate the display panel through the first polarization plate. The illumination device includes a light modulation layer provided in a clearance between first and second transparent substrates, the light modulation layer being configured to exhibit scattering property or transparency of the light from the light source depending on a magnitude of an electric field. The light modulation layer includes a first portion having optical anisotropy, and relatively high responsiveness to the electric field, and a second portion having optical anisotropy, and relatively low responsiveness to the electric field. The light modulation layer generates polarized light when the light modulation layer exhibits the scattering property, the polarized light having a polarization component mainly in a first direction that is parallel to a transmission axis of the first polarization plate.

    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.
