Abstract
For the purpose of producing liquid-crystal wristwatches whose entire display surface can be read even when they are in a tilted state, provision is made of a front fibre-optic cell plate (14) with light-conducting fibres (14a) running perpendicular to the display surface. The display device has, in addition, a cholesteric guest/host liquid-crystal cell. The front fibre-optic cell plate (14) has an optical resolution of 5 to 100 lines per millimetre and a numerical aperture (NA) of 0.5 to 1.05. The measures described furthermore permit the realisation of flat digital watches which are aesthetically pleasing, i.e. provided with dished/cambered front cell plates. <IMAGE>
