Abstract
A lighting device includes: a light guide plate; a light source; and a light modulation element disposed on a surface of 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, a first electrode provided on a surface of one of the transparent substrates, a second electrode provided on a surface of the other of the transparent substrates, and a light modulation layer, provided in a gap between the transparent substrates, exhibiting a light-scattering property or a light-transmitting property concerning light from the light source depending on intensity of an electric field. One or both of the first and second electrodes include partial electrodes. First partial electrodes of the partial electrodes are adjacent to second partial electrodes of the partial electrodes, and have irregular shapes on edges adjacent to the second partial electrodes.
