Claim 5:
6. A method of driving a polymer dispersion type liquid crystal panel that includes
a pair of transparent substrates;
a pair of transparent electrodes provided between the pair of transparent substrates; and
a liquid crystal layer formed by filling a polymer dispersion type liquid crystal between the pair of transparent electrodes, the method comprising:
applying a direct current voltage that periodically inverts a polarity between the pair of transparent electrodes, to set the liquid crystal layer to a non-scattering state or a scattering state,
wherein
a voltage transition time at the time of inverting the polarity is 100 milliseconds or less and
a flicker rate of a flicker occurring at the time of inverting the polarity is 2% or less.
