A flat display for a mobile radio telephone or another autonomous electrical
device,
with a display surface on which information can be displayed. The display can be
electrically controlled to make the entire display surface, or only a portion thereof,
reflecting. Alphanumerical and/or advertising information can be displayed on the
remaining, non-reflecting portion of the display surface. The mobile radio telephone
can also be used as a practical pocket mirror. Advertisements and important information,
for example service provider identifications, can be displayed particularly effectively
on a reflecting background.
