An antiferroelectric liquid crystal cell having a high-speed response and wide viewing angle characteristic free of an image sticking phenomenon is provided. This antiferroelectric liquid crystal cell is composed of an antiferroelectric liquid crystal material held between a pair of parallel substrates. The antiferroelectric liquid crystal material filled between the parallel substrates has such a characteristic that when a sinusoidal voltage value with a changing reference frequency is applied to the antiferroelectric liquid crystal cell, the imaginary part of the complex dielectric constant obtained by Fourier transform of the output voltage value output from the antiferroelectric liquid crystal cell has no local maximum value within the reference frequency range of 100 Hz to 5 kHz. In other words, this characteristic is similar to a characteristic such that when the real part and the imaginary part of the complex dielectric constant are plotted by using a Cole--Cole plot for each frequency, a characteristic curve having no local maximum value within the reference frequency range of 100 Hz to 5 kHz is obtained.
