Abstract

In a display device, for an electronic digital watch, having an indicating layer which can be varied optically by electric fields, e.g. liquid crystal between two carrier plates, the outer carrier plate is transparent and carries transparent electrodes which are selectively controlled to produce an alpha-numeric display of time and calendar data and in addition, to produce reference symbols e.g. 50, 51, 52, 30a-30c (Fig. 3). The symbols indicate the current function or mode selected (e.g. geographical time, alarm time, chronograph) and the nature of the information in the alpha-numeric displays.
