Abstract:
1. A parallax barrier device comprising a pair of transparent-electrode substrates each provided with a transparent electrode, and a pair of polarizers sandwiching the pair of transparent-electrode substrates therebetween, wherein a barrier light-shielding part and a light-transmitting part are formed in a gap between the pair of transparent-electrode substrates, a liquid crystal layer is formed in the barrier light-shielding part, a resin layer having the property of transmitting light and not serving as a liquid crystal layer is formed in the light transmitting part, the barrier light-shielding part and the light-transmitting part are alternately arranged along a direction in a plane parallel to the pair of transparent-electrode substrates; the directions of transmission easy axes of the pair of polarizers are approximately parallel to each other, and the barrier light-shielding part is configured to change a polarization state of light entering the liquid crystal layer according to a distribution state of liquid crystal molecules so that a polarization state of light which has passed through the liquid crystal layer differs from a polarization state of light which has passed through the resin layer having the property of transmitting light.
