Abstract:
A liquid crystal display apparatus includes a liquid crystal modulation element having a liquid crystal layer and first and second electrodes, and a controller performs control for an electric potential difference applied between the electrodes such that an electric field applied to the liquid crystal layer is inverted between positive and negative. The controller switches the control between first control and second control. The first control controls the electric potential difference such that one of an absolute value of a time-integrated value of the positive electric field applied to the liquid crystal layer and an absolute value of a time-integrated value of the negative electric field applied thereto is larger than the other, and the second control controls the electric potential difference such that the other absolute value of the time-integrated value is larger than the one absolute value of the time-integrated value.
