1. An image display system comprising:

  • a display unit that spatially combines a first polarized image generated by first polarized light and a second polarized image generated by second polarized light whose polarized light component is different from that of the first polarized light and that displays a combined polarized image;

    a display control unit that causes the display unit to multiplex-display a plurality of different images in a time division manner concerning each of the first and second polarized images; and

    an optical shutter that selectively transmits only a polarized image corresponding to a selected image arbitrarily selected from among the plurality of different images,whereinthe display control unit outputs a control signal that indicates timing of switching of the plurality of different images,the optical shutter specifies a display period of the selected image on the basis of the control signal, andthe optical shutter transmits, of the first polarized light and the second polarized light, polarized light used for generation of the selected image and blocks the other polarized light in the display period of the selected image and blocks the first polarized image and the second polarized image in a period other than the display period of the selected image.
