Liquid crystal shutter device and picture display system

A picture display system having a picture display performing, in a time-divisional manner, a switching of a plurality of picture streams to select one of the picture streams and performs picture display based on the selected picture stream, and one or more liquid crystal shutter devices each performing an opening action and an closing action in synchronization with the switching of the plurality of picture streams in the picture display, each of the liquid crystal shutter devices comprising:

• two shutter mechanisms each including a liquid crystal device and configured so as to alternately perform an opening action and a closing action in a time-divisional manner, the opening action allowing incident light to pass through corresponding one of the shutter mechanisms, the closing action allowing the incident light to be blocked;
• and
• a drive section controlling a switching operation between the opening action and the closing action for each of the shutter mechanisms, while driving the liquid crystal device in each of the shutter mechanisms by means of a polarity inversion method in which a polarity of a drive voltage is alternately inverted,
• wherein the drive section inverts the polarity of the drive voltage in a period of the opening action.
