Abstract:
1. A display device, which is arranged to display different images to a plurality of different viewpoints, comprising: an image generating unit arranged to generate the images and to emit light beams corresponding to the images thus generated; and a parallax barrier including a transmissive section through which the light beams emitted from the image generating unit and heading in a particular direction pass, and a barrier light-blocking section which blocks the light beams heading in directions other than said particular direction; wherein the display device has a structure such that, in cases where a first image is an absolute white image, a direction in which a luminance is maximum being regarded as a main viewing direction for the first image, a luminance Ld in the main viewing direction for the first image in cases where the first image is an absolute black image and other image is an absolute white image, and a luminance Lb in the main viewing direction for the first image in cases where the first image and the other image are absolute black images satisfying a relationship represented by the following formula: a relationship represented by the following formula is satisfied: where T denotes a transmittance of the barrier light-blocking section for the light beams.
