    摘要： A light control element capable of controlling deflection of light output through a light guide plate to a desired output viewing angle is provided. A light control element (prism sheet) has a plane of incidence on one surface thereof, and a plane of output on the other surface thereof. The plane of incidence is formed as having thereon a number of prism portions arrayed in parallel. Each of the prism portions has a first prism surface allowing incidence of light, and a second prism surface where the light entering through the first prism surface is reflected by total reflection on the inner side. The second prism surface has an outwardly-swelled curved profile, formed with a curvature that allows the light to output through the plane of output at a second output viewing angle wider than a first output viewing angle of a case where the second prism surface is flat.

    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.
