ANTIFERROELECTRIC LIQUID CRYSTAL CELL

摘要

An antiferroelectric liquid crystal cell in which an antiferroelectric liquid crystal is sandwiched between a pair of substrates is improved in contrast. The antiferroelectric liquid crystal cell has a layered structure such that in the case where a voltage outputted on application of a sine-wave voltage as a reference frequency to the liquid crystal cell is transformed by Fourier transform, the transformed output voltage includes laps of components of frequencies which are odd-number times and even-number times the reference frequency, and its optical path length is 100 to 800 nm.
