Display device

A display device, which is capable of displaying a first image and a second image to a plurality of different viewpoints, having a structure such that, in cases where the 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 the second image is an absolute white image, and a luminance Lb in the main viewing direction of the first image in cases where the first image and the second image are absolute black images satisfying a relationship represented by the following formula:

• (Ld−Lb)/Lb≦2.5;
• the display device further comprising:
• an image generating unit arranged to generate the first image and the second image and emitting light beams corresponding to the images thus generated;
• and
• a parallax barrier including a transmissive section through which a light beam having been emitted from the image generating unit and heading in a particular direction pass, and a barrier light-blocking section which blocks light beams heading in directions other than said particular direction;
• wherein
• a relationship represented by the following formula is satisfied:
• log(1/T)≧4
• where T denotes a transmittance of the barrier light-blocking section for the light beams.

A display device, which is capable of displaying different images to a plurality of different viewpoints, comprising:

• an image generating unit arranged to generate the images and emitting light beams corresponding to the images thus generated;
• and
• a parallax barrier including a transmissive section through which a light beam having been emitted from the image generating unit and heading in a particular direction pass, and a barrier light-blocking section which blocks light beams heading in directions other than said particular direction;
• wherein
• said barrier light-blocking section is made of a resin;
• a relationship represented by the following formula is satisfied:
• log(1/T)≧4
• where T denotes a transmittance of the barrier light-blocking section for the light beams;
• and
• a relationship represented by the following formula is satisfied:
• S′/S≦0.2
• where S denotes an intensity of a light beam irradiated onto the barrier light-blocking section, and S′ denotes an intensity of a light beam reflected by the barrier light-blocking section.
