ABSTRACT:
A stereoscopic image display apparatus includes: an image display unit22for displaying image information corresponding to parallax in a first division and a second division; a divided wave plate filter unit12having a frame41and disposed adjacent to the first division and the second division of the image display unit, for rotating polarized light of the image information from the first division to a direction different from polarized light of the image information from the second division; and position adjusting means35R and35L for acting on the frame of the divided wave plate filter unit and thereby allowing adjustment of a relative position between the image display unit and the divided wave plate filter. Also, a display apparatus includes: a filter unit used in a state of being laid over an image display unit for displaying image information in a first division and a second division; and a filter frame portion disposed integrally around a periphery of the filter unit; wherein the filter unit has a first wave plate in a region corresponding to the first division of the image display unit for rotating polarization direction of the image information from the first division to a direction different from polarization direction of the image information from the second division; and the filter frame portion has an alignment mark formed therein by a second wave plate for rotating polarization direction.
