An optical display system includes: a light source; a display panel including multiple pixel regions, each of which can modulate light; and an optical shifter, which is disposed so as to receive an outgoing light ray of the display panel and optically shift an image on the display panel on a frame-by-frame basis. The optical shifter includes a first element for selectively changing the polarization direction of the outgoing light ray of the display panel, and a second element, which exhibits one of multiple different refractive indices according to the polarization direction of an incoming light ray. A polarization corrector, which changes the polarization direction of the outgoing light ray of the display panel into a direction that is either parallel to, or perpendicular to, a direction in which the image is shifted, is provided between the display panel and the optical shifter.
