摘要： An anti-ferroelectric liquid crystal cell which has characteristics of high-speed response and broad visual field angle and generates no image persistence. This anti-ferroelectric liquid crystal cell is constituted by an anti-ferroelectric liquid crystal material narrowly held between a pair of parallel substrates. The anti-ferroelectric liquid crystal material injected between the parallel substrates has such a characteristic that when a sine voltage value obtained by changing a reference frequency is applied to the anti-ferroelectric liquid crystal cell, an imaginary part of a complex dielectric constant obtained by carrying out Fourier transform of an output voltage value outputted from the anti-ferroelectric liquid crystal cell has no maximum value within a range of reference frequency of 100 Hz to 5 kHz. In other words, this characteristic is equivalent to such a characteristic that when a real part and an imaginary part of the complex dielectric constant are plotted by Cole-Cole plot for every frequency, a curve having no maximum value within the range of reference frequency of 100 Hz to 5kHz is obtained.
