摘要：
A lighting device includes: a light guide plate; a light source disposed on a side face of the light guide plate; and a light modulation element disposed on a surface or in the inside of the light guide plate and adhered to the light guide plate. The light modulation element has a pair of transparent substrates disposed separately and oppositely, a pair of electrodes provided on respective surfaces of the pair of transparent substrates, and a light modulation layer provided in a gap between the pair of transparent substrates. The light modulation layer includes a first region, having optical anisotropy, responsive to an electric field, and a second region, having optical anisotropy, unresponsive to an electric field. The second region has a striped structure with average striped texture size of 0.05 μm to 10 μm both inclusive in a short axis direction.
