摘要： 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.

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.

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 control section of a portable phone controls a display on a main display section with a viewing angle that is variable. The control section includes: a viewing-angle obtaining section to obtain viewing-angle information about the viewing-angle of the main display section; and a viewing-angle display control section to control an image display section of the main display section to display the viewing-angle information obtained by the viewing-angle obtaining section. The viewing-angle information is obtainable from a viewing-angle control section. The viewing-angle control section controls a viewing-angle changing section. The viewing-angle changing section changes the viewing angle. It is possible to obtain the viewing-angle information as a result that an operation section conducts an operation to change the viewing angle, and/or as a result that an application executing section executes a predetermined application. The foregoing allows a user to find out a viewing-angle state of the display device by looking at a display screen of the display device from the front.
