A liquid crystal display panel 1 for displaying non-identical images along non-identical lines of sight includes: a parallax barrier (2) having light-transmitting sections (21) and light-blocking sections (22) alternately arranged in a lattice manner with each of the light-transmitting sections (21) provided with a condenser lens (23) having a long axis parallel to a long side A of the light-transmitting section (21); and a back polarizing plate (4) and a front polarizing plate (5) disposed on a light incidence side and a light exit side, respectively, each of the polarizing plates (4, 5) having its absorption axis set in a parallel or orthogonal relationship with the long axis of the condenser lens (23). This provides: a liquid crystal display panel capable of presenting non-identical images along non-identical lines of sight with high contrast; and a liquid crystal display device including such a liquid crystal display panel.

On the display surface side of a DV display apparatus which performs image separation via a parallax barrier, a normally-white TN liquid crystal section is arranged such that a viewing angle direction heads toward the passenger seat. In a case where display is performed for both the driver's seat and the passenger seat, a drive voltage of the TN liquid crystal section is switched off. In a case where display for the driver's seat is set to non-display and an image is displayed only for the passenger seat, a halftone voltage is applied as the drive voltage of the TN liquid crystal section. In the case where display for at least one display direction is set to non-display in a display apparatus which can display different images in plural display directions by using a common display screen, it is possible to prevent image light for other directions from leaking to the non-display direction.

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.

A portable phone has a main LCD and a SW-LCD, provided on a path of light to be transmitted by the main LCD, which electrically switches between (i) an image to be seen in a single image display mode and (ii) an image to be seen in a multiple image display mode. In the multiple image display mode, the display switch makes it possible that (a) the image displayed by the image display is seen from a front direction and (b) an image obtained by superimposing, onto the image displayed by the image display, a switching image formed by the display switch is seen from an oblique direction. The switching image is formed by providing, with at least one of a pair of transparent electrode films for applying a voltage to a liquid crystal layer, a patterning having an area larger than 50% of an area of a display screen.

A view angle control element capable of limiting a view angle without degrading image quality (front quality) when seen from a front side and a display device provided with the view angle control element are provided. A liquid crystal display device (1) includes a liquid crystal panel (10), and a view angle control film (20) that controls a view angle of the liquid crystal panel (10). The view angle control film (20) is a laminated film including at least a liquid crystal film (21) and a linearly polarizing plate (22). In the liquid crystal film (21), liquid crystal molecules are solidified while being aligned with major axes tilted in a predetermined azimuth angle direction from a normal direction of a film surface. The linearly polarizing plate (22) of the view angle control film (20) and the linearly polarizing plate (14) of the liquid crystal panel (10) are placed so that polarization transmission axes thereof cross a major axis direction of the liquid crystal molecules when seen from the normal direction.

In a display device, when a first image is an absolute white image, a direction in which a luminance is maximum is 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 other image is an absolute white image, and a luminance Lb in the main viewing direction for the first image in cases where the first image and the other image are absolute black images satisfy a relationship represented by Formula (1): (Ld−Lb)/Lb≦2.5 (1). This makes it possible to realize a display device, which is capable of displaying different images to a plurality of different viewpoints and has an improved function of separating the images in the different display directions.

A dual-view liquid crystal display device (1) includes: screen scaling-down sections (32, 42) for forming child screens (11a, 12a), i.e., screens obtained by scaling down parent screens (11, 12); and screen combining sections (33, 34) for combining the child screens (12a, 11a) with the parent screens (11, 12), respectively. This makes it possible to know the content of one screen while viewing the other screen.

摘要:
In a SW-LCD, an orienting film is divided into first and second regions having different directions of orientation, and a transparent electrode film is also patterned so as to be divided into regions respectively corresponding to the first and second regions. In the first region, a viewing angle in right and left directions is controlled. In the second region, a viewing angle in upper and lower directions is controlled. With this, a display device is realized which makes it possible to switch between a wide viewing angle display mode and a narrow viewing angle display mode, which controls a viewing angle in both upper and lower directions and in right and left directions in the narrow viewing angle display mode, and which makes it possible to prevent an image from being seen obliquely from the right and left directions and from the upper and lower directions.
