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. Furthermore, a first polarization plate serving as a reflective polarization plate is provided between the SW-LCD and the main LCD, and a second polarization plate is provided on a front surface side of the SW-LCD. The SW-LCD has a liquid crystal layer to which a voltage is applied in the multiple image display mode. With this, an image displayed by an image display can be seen from a front direction. In addition, the image displayed by the image display means is blocked by the second polarization plate when the image is seen from the an oblique direction, and outside light from the oblique direction is reflected by the first polarization plate, so that a mirror surface display is carried out.
