Abstract:
1. A liquid crystal display apparatus, comprising: a liquid crystal modulation element configured to modulate light from a light source, and including a first electrode, a second electrode, a liquid crystal layer disposed between the first electrode and the second electrode, a first alignment film disposed between the first electrode and the liquid crystal layer, and a second alignment film disposed between the second electrode and the liquid crystal layer; and a controller configured to provide a first potential to the first electrode and a second potential to the second electrode such that the sign of an electric field generated in the liquid crystal layer is cyclically inverted and to make the liquid crystal modulation element perform a light modulation operation, wherein while the light source is turned off, the controller provides a third potential to the first electrode and a fourth potential to the second electrode, such that the difference between the third potential and the fourth potential has a constant sign but a variable magnitude in an in-plane direction of the liquid crystal layer.
