Patent ID: 6961043

Claim:
A liquid crystal display comprising: a ferroelectric liquid crystal material which is held between a pair of electrode substrates and whose optical response is asymmetric with respect to the polarity of a voltage applied; a signal applying section which applies an image signal to a pixel of said liquid crystal material for every two fields forming one frame; and a polarity controller which reverses the polarity of the image signal in one frame period, said polarity controller being configured that the polarity of the image signal is reversed in a selected one of first and second polarity control manners, said first polarity control manner initiating an amplitude change of the image signal from a polarity in which a larger response of said liquid crystal material is obtainable, said second polarity control manner initiating an amplitude change of the image signal from a polarity in which a smaller response of said liquid crystal material is obtainable, and said selected polarity control manner being smaller in the total of brightness deviation generated in a frame immediately after the amplitude change for each of predetermined brightness transitions.
