Abstract
A parallax composite image displayed by image display means may be observed as predetermined parallax image at predetermined position by reflecting and guiding light from light source means and by using a diffusion pattern in which diffusion patterns are engraved at predetermined intervals to diffuse and transmit incident light on the diffusion pattern to the image display means. A fine notched structure is provided to cyclically and symmetrically vary the diffusion patterns in the horizontal direction. A structure is provided to control an amount and range of blur of pixels visible through light diffused toward the image display means by the diffusion pattern to which recesses and protrusions are added. By evaluating and adjusting a cycle of the notched structure so as to be appropriate, resultant adverse effects from the notched structure itself may be suppressed. Bright-dark patterns having a relatively long cycle may be reduced without increasing crosstalk.
