Claim:
1. A display comprising: a lighting unit outputting illumination light; a display panel modulating the illumination light to output a picture; and a drive circuit driving the lighting unit and the display panel, wherein the lighting unit includes the light modulation device includes one or both of the pair of electrodes have a plurality of partial electrodes arranged in a direction orthogonal to a light incident surface of side surfaces of the light guide plate, the light incident surface receiving light from the light source, the light modulation layer totally or partially exhibits scattering property or transparency to the light from the light source depending on a magnitude of an electric field generated by the electrodes, and the drive circuit sequentially drives the plurality of partial electrodes on a predetermined unit basis such that a region exhibiting the scattering property of the light modulation layer is sequentially transferred from unit to unit in the direction orthogonal to the light incident surface while the remaining units exhibit transparency, wherein the drive circuit adjusts a light amount of the light source depending on a distance of the partial electrode to be driven of the plurality of partial electrodes from the light source.
