Claim 0:
1. An electronic apparatus comprising:
a light source with an output light flux of 5000 lumen to 20000 lumen;
a light splitting member configured to split light from the light source;
a first liquid crystal apparatus configured to modulate first light split by the light splitting member; and
a second liquid crystal apparatus configured to modulate second light split by the light splitting member, wherein
the first liquid crystal apparatus includes:
a first liquid crystal layer
a first pixel electrode provided in a display region and configured to be supplied with an image signal at a first frequency; and
a first electrode provided in a region outside the display region and configured to be alternately supplied with a positive polarity potential with a potential higher than a predetermined potential and a negative polarity potential with a potential lower than the predetermined potential at a second frequency lower than the first frequency such that a positive polarity period in which the positive polarity potential is supplied and a negative polarity period in which the negative polarity potential is supplied have a same length, and
the second liquid crystal apparatus includes:
a second liquid crystal layer;
a second pixel electrode provided in a display region of the second liquid crystal apparatus and configured to be supplied with an image signal at the first frequency; and
a second electrode provided in a region outside the display region and configured to be alternately supplied with a positive polarity potential with a potential higher than a predetermined potential and a negative polarity potential with a potential lower than the predetermined potential at a third frequency lower than the first frequency such that a positive polarity period in which the positive polarity potential is supplied and a negative polarity period in which the negative polarity potential is supplied have different lengths.
