Abstract
A display includes a ferroelectric liquid crystal material having an asymmetric polarity response property, a section which applies an image signal to a pixel of the material for every two fields forming one frame, and a controller which reverses the polarity of the signal in one frame period. Particularly, the controller is configured that the polarity of the signal is reversed in a selected one of first and second manners, the first manner initiating a signal amplitude change from a polarity in which a larger response of the material is obtainable, the second manner initiating a signal amplitude change from a polarity in which a smaller response of the material is obtainable, and the selected manner being smaller in the total of brightness deviation generated in a frame immediately after the change for each of predetermined brightness transitions.
