摘要： 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.

摘要： A viewing angle control element of the present invention contains transparent regions 23 having a transmittance T1 and light shield regions 24 capable of switching between a transmittance T2 and a transmittance T3 which is less than T1 and T2 according to an external signal. Each of the transparent regions 23 and the light shield regions 24 is positioned opposite to one of pixels. Displays are produced at or close to the original brightness of the image display element in wide viewing angle mode, whereas in narrow viewing angle mode, light transmission is limited to achieve narrow viewing angles. This is in contrast with other viewing angle control elements which produce displays at or close to the original brightness of the image display element in narrow viewing angle mode, whereas in wide viewing angle mode, light is diffused or otherwise modified to achieve wide viewing angles. Thus, the viewing angle control element is capable of achieving both wide viewing angles and narrow viewing angles, and still preventing image quality deterioration at wide viewing angles due to decreased brightness of the image display element.

摘要： A first optical-path changing layer is provided, on a front-face side of a rear-face side transparent substrate including a light source on one side face thereof. The first optical-path changing layer has a refractive index substantially equal to that of the transparent substrate, and includes predetermined protrusions and predetermined depressions. Further, a low refractive-index layer is provided on a front-face side of the first optical-path changing layer. The low refractive-index layer is in contact with the protrusions and the depressions of the first optical-path changing layer, and has a smaller refractive index than the refractive index of the first optical-path changing layer. Further, a second optical-path changing layer is provided on a rear-face side of the rear-face side transparent substrate. The second optical-path changing layer includes predetermined protrusions and predetermined depressions.

摘要： An ATM of the present invention includes a liquid crystal display panel having, between two transparent substrates, (i) an image forming layer including at least a liquid crystal layer and a pixel section in which RGB pixels are arranged in a matrix manner, and (ii) a plurality of barriers (16) for splitting a display image formed by the image forming layer into a plurality of images each having a specific viewing angle. The plurality of barriers are provided so as to face the image forming layer. The plurality of barriers (16) are extended in a horizontal direction (lateral direction) parallel to the surfaces of the transparent substrates, and provided at substantially regular intervals in a direction perpendicular to the horizontal direction, parallel to the surfaces of the transparent substrates (i.e., in a longitudinal direction). This makes it possible to provide an ATM that prevents a peep at private information such as a secret number without giving, whichever direction a display is viewed, a false recognition that the display is in a resting state.
