Abstract
The device displays an hour hand and a minute hand on a twelve hour dial and comprises a layer of electro-optical material having on one face an inner ring of 10 sectorial plate electrodes B1 etc, each subtending an angle of 36 DEG and a corresponding outer ring of 10 plate electrodes B11 etc. On the other face there are sixty radial segments electrodes arranged in ten groups of six segments. Each group is opposed to a respective one of the ten plates. The segments are connected in six meandering circuits M1 to M6 so that, in proceeding one way round the dial, the segments of the said groups pertaining to the circuits M1 to M6 and then to the circuits M6 to M1 and so on in alternation round the dial. As can be seen from the steady lines demarcating the plate electrodes, these electrodes are assymetrical relative to the 12 o'clock axis of the dial so that there is a boundary between two adjacent plates in each ring angularly offset from that axis by a whole number of the segments, namely one segment as illustrated.
