<p>The liquid crystal display apparatus includes a liquid crystal modulation element (2R, 2B, 2G) including first and second electrode (103, 107), a liquid crystal layer (105) disposed between the first and second electrodes, a first alignment film (104) disposed between the first electrode and the liquid crystal layer, and a second alignment film (106) disposed between the second electrode and the liquid crystal layer. The apparatus further includes a controller (3) that respectively provides first and second electric potentials to the first and second electrodes such that a sign of an electric field generated in the liquid crystal layer is cyclically inverted in a modulation operation state. The controller respectively provides third and fourth electric potentials to the first and second electrodes such that the sign of the electric field is fixed in a state other than the modulation operation state. The apparatus can avoid an influence by cumulated charged particles without adding a new member.</p> |
