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.

摘要： A display section of a portable phone includes a first polarizer, a switching panel section, a reflective polarizer, and a main panel section. The switching panel section has a liquid crystal layer including a plurality of regions having at least two different alignment directions. This makes it possible, by utilizing the difference in the alignment direction of the liquid crystal layer, to make the image difficult to observe by a sight-line from an oblique direction. Furthermore, it is also possible, by utilizing the mirror-surface displaying caused by the reflective polarizer, to make the image significantly difficult to observe.

摘要： In a parallax barrier DV (Dual View) display apparatus, a TN (Twisted Nematic) liquid crystal display panel is adopted as a display device for display images. The TN liquid crystal display panel includes a pair of opposing substrates, a liquid crystal layer sandwiched therebetween, orientation films arranged to orient liquid crystal molecules constituting the liquid crystal layer, and electrodes arranged to independently apply electric fields to areas of the liquid crystal layer which correspond to respective pixels. The orientation films are oriented in such a manner that liquid crystal molecules in the aforesaid areas are oriented so that display directions of the pixels are parallel or substantially parallel to a viewing angle direction. This arrangement improves image separation capability in all display directions, in a DV (Dual View) display apparatus displaying different images in respective display directions, by a single display screen.

摘要： A first transparent electrode film, which is a component of a SW-LCD for viewing angle control, is used as a touch panel. When a contacting object contacts the surface of the first transparent electrode film, a position detector detects currents flowing from plural parts of the first transparent electrode film so as to detect the contacting position of the contacting object, with reference to the detection result. With this, it is possible to provide a built-in touch sensor display device which is thin, lightweight, and low-cost, a viewing angle control device, and an electronic device.

摘要： A display device (1a) of the present invention includes a displaying section (10), an image generating section (2) for generating an image signal, and a parallax barrier aperture array (17), distinction means (3) for judging whether cross talk of an image of another-pixels reaches a level at which the cross talk is perceived by a viewer of an image of self-pixels, and adjustment means (4) for adjusting the pixel signals of the another-pixels so as to eliminate the cross talk, in a case that the distinction means (3) judges the cross talk of the image of the another-pixels reaches to the perceivable level. This provides a display device and a vehicle equipped therewith, both of which display, on a single display screen, different images in a plurality of display directions and thus are capable of providing excellent display environments wherein the viewer of an image displayed in one display direction does not perceive cross talk of an image displayed in another direction.

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 control section of a portable phone controls a viewing-angle changing section that changes a viewing angle of an image display section. The control section controls the viewing angle of the image display section on the basis of a status of use of various devices. Specifically, the control section includes: a device-in-use detecting section to detect use of the devices; a storage section to store a device/viewing-angle matching table containing a correspondence relationship between a device to be used and a viewing angle; a viewing-angle retrieving section to retrieve, from the table, a viewing angle for the device detected being in use by the device-in-use detecting section; and a viewing-angle control section to control the viewing-angle changing section on the basis of the viewing angle retrieved by the viewing-angle retrieving section. The foregoing allows the viewing angle to be controlled automatically on the basis of the status of use, with a few settings.

摘要： A display device includes: a main LCD; a SW LCD, disposed on an optical path of light transmitting through the main LCD, for electrically switching a visible image between a single image display mode and a multiple image display mode; a first polarizer; and a second polarizer. The major axis direction of liquid crystal molecules in the liquid crystal layer of the SW LCD is always substantially parallel to the polarization direction of light after transmission through the first polarizer when projected from the normal to the substrates. At least some of the liquid crystal molecules in the liquid crystal layer are controlled in terms of alignment direction so that the major axis direction of the liquid crystal molecules is substantially parallel to the substrates in the single image display mode and tilted from the substrates in the multiple image display mode.
