Abstract
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.
