Abstract

A display device for an electronic timepiece has 60 radially arranged segment electrodes (27a) Fig. 2 and three rings of common electrodes (28a, 28b, 28d) Fig. 3. A liquid crystal material is disposed between the segment electrodes and the common electrodes and the arrangement produces a time display simulating that given by a timepiece with mechanical hands. The outermost common electrode ring (28d) constitutes an electro- optical graduated time scale which is either permanently energised or can be used to indicate seconds. <IMAGE>
