Abstract
In one embodiment, a liquid crystal shutter includes a first liquid crystal panel for left eye and a second liquid crystal panel for right eye. Each liquid crystal panel includes a pair of electrode substrates and a liquid crystal layer held between the electrode substrates. A driving circuit switches the first and second liquid crystal panels between a transmissive state and a non-transmissive state by turns by applying a voltage to the first and second liquid crystal panels while inversing the polarity of the voltage applied between the pair of the electrode substrates at least once during a period in the transmissive state.
