Abstract
Provided is an information display apparatus that significantly improves light resistance with respect to sunlight. The information display apparatus, which displays video-image information on a projection surface by a virtual image, includes in a housing partly having an opening: a video-image-light generator that generates video-image light for displaying the video-image information; a video-image-light processor that performs a predetermined optical processing to a video image generated by the video-image-light generator; and a projector that projects, onto the projection surface through the opening of the housing, the video-image light optically processed by the video-image-light processor so that a viewer is capable of virtually recognizing the video-image information as a virtual image in front of the projection surface, wherein a light path in the housing is provided with a suppressor selectively suppressing a P-polarizing component of light in a visible light region.
