Abstract

There is provided a liquid crystal driving apparatus which includes a first substrate and a second substrate, a first counter electrode that is provided on the first substrate so as to face the second substrate, a second counter electrode that is provided on the second substrate so as to face the first substrate, a polymer network liquid crystal layer that is enclosed between the first substrate and the second substrate, and a drive circuit configured to ON-drive the first counter electrode and the second counter electrode by applying a rectangular wave voltage for driving the second counter electrode upon inverting a phase and shifting forward or backward by a minute time Δt with respect to a rectangular wave voltage for driving the first counter electrode.
