A stereoscopic display device includes: a parallax barrier in which light transmission parts that transmit light and light shielding parts that block light are formed alternately, and a display panel that displays a stereoscopic image. A plurality of pixels for displaying the stereoscopic image are formed on the display panel. Each pixel includes a plurality of color forming subpixels that contribute to the color formation of the stereoscopic image, and a contrasting subpixel that contributes to the contrast of the stereoscopic image. In each pixel, the contrasting subpixel is positioned at both ends of the pixel in a direction in which the light transmission parts and the light shielding parts are arranged alternately. In each pixel that overlaps the light shielding part when the display panel is viewed from front, the contrasting subpixel is positioned at both ends of the light shielding part.

A multiplex image display device prevents onscreen input buttons from appearing at the same positions. A 'command area' refers to an area of the display screen where the user can enter a command for manipulating one of images being simultaneously displayed on the single display section for individual viewing from different directions. In the multiplex image display device, the positioning control section controls the positioning of the command areas so that a command area for one of the images being simultaneously displayed on the display section is displayed at a different (i.e., non-overlapping) position on the display section from a command area for another one of such images.

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 () 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 () 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.

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):()/&#x2266;2.5&#x2003;&#x2003;(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 control section of a portable phone controls a viewing-angle changing section that changes a viewing angle of an image display section-and controls the viewing angle of the image display section on the basis of a status of use of various devices. 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.

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.

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.

When an apparatus C which shares the media with apparatuses A and B desires to transmit an RTS packet, apparatus C inhibits transmission of the RTS packet for a fixed waiting time Tm plus a transmission inhibition period which varies depending on a type of a packet in a sensed carrier. In other words, when apparatus C senses an RTS packet of apparatus A, apparatus C inhibits transmission for a packet transmission inhibition period 101 resulting from reception of RTS. When apparatus C senses a CTS packet of apparatus B, apparatus C inhibits transmission for a packet transmission inhibition period 102 resulting from reception of CTS. When apparatus C senses a data packet, apparatus C inhibits transmission for a packet transmission inhibition period 103 resulting from reception of a data packet. When apparatus C senses an ACK packet of apparatus B, apparatus C inhibits transmission for a packet transmission inhibition period 104 resulting from reception of an ACK. As a result, a data communication apparatus which achieves efficient communication between a plurality of data communication apparatuses which share the same media is provided.

Data communication apparatus achieving efficient use of the media

A communication apparatus includes a memory. The memory stores the protocol of an ASK system and the protocol of an IrDA system. These protocols require predetermined time periods of T1 and T2 prior to establishing a connection with a station of the other party. The memory further stores time periods of Ra, Rb, Sa, and Sb, where the relationship of (Ra+Rb).noteq.(Sa+Sb), Sa&gt;T1, Sb&gt;T2, Rb&gt;T2 is established. The communication apparatus further includes a transmission circuit and a reception circuit for the ASK system, a transmission circuit and a reception circuit for the IrDA system, a timer, and a control circuit. The control circuit controls the transmission circuit, the reception circuit, and the timer while referring to the stored contents of the memory. The control circuit carries out a 'handshaking' procedure with the station of the other party, alternately trying the ASK protocol and the IrDA protocol until it is determined which of the two protocols the two stations have in common, and setting a flag signal to select the fastest transmission protocol which the two stations have in common. The selected protocol is thereafter used for communication between the two stations.
