(57) ABSTRACT

A parallax barrier device includes a pair of transparent-electrode substrates each provided with a transparent electrode. 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 is formed in the light-transmitting part. The barrier light-shielding part separates light for a first image viewed from a first direction and light for a second image viewed from a second direction different from the first direction. The light-transmitting part transmits the light for the first image and the light for the second image.
