<p>The purpose of the present invention is to provide a light control device having a fast light control of a transmitting state and a light shielding state and a retention of the transmitting state at a voltage non-applying state which are compatible with each other, and is to provide a driving method thereof. The light control device comprises: a first substrate 11 and a second substrate 12, a first electrode 12 formed on said first substrate 11, a second electrode 14 formed on said second substrate 12, a suspension 17, and a driving circuit 100, wherein said suspension 17 comprises a light controlling particle and a dispersion medium, said light controlling particle 16 has an optical anisotropy and is electrostatically charged, an electric potential difference is arranged between said first electrode 13 and said second electrode 14, and said second electrode 14 is constituted of periodically aligned electrodes having a same electric potential.</p> |
