ABSTRACT:
An electronic timepiece in which an optical hand display device is composed of a plurality of segment electrodes of the shape of hands that are radially arrayed and opposing common electrodes that are divided into groups via a liquid crystal, the segment electrodes located at predetermined positions are electrically connected together, the segment electrodes being divided into groups each consisting of a predetermined number of segment electrodes, and time information is displayed by hands for each predetermined digits in a time-divisional manner. According to the electronic timepiece of the present invention, the number of terminals to the electrodes is reduced, and time can be clearly displayed by hands requiring reduced number of selection voltages.
