<P>PROBLEM TO BE SOLVED: To provide an image display apparatus which can effectively cause an image to be visually perceived. <P>SOLUTION: An image display apparatus 291 alternately switches between a first period and a second period. In the first period, the first optical modulation device 250A is caused to form a first image light, and the second optical modulation device 250B is caused to form a second image light; and in the second period, the first optical modulation device 250A is caused to form the second image light, and the second optical modulation device 250B is caused to form the first image light. A polarization control device 293 controls a polarization switching device 26 to operate, in the first period, causing the first image light from the first optical modulation device 250A to switch to a first polarized light, and causing the second image light from the second optical modulation device 250B to switch to a second polarized light, and in the second period, causing the second image light from the first optical modulation device 250A to switch to the second polarized light, and causing the first image light from the second optical modulation device 250B to switch to the first polarized light. <P>COPYRIGHT: (C)2011,JPO&INPIT |
