Abstract

The invention concerns with an electronic timepiece provided with digital display means including an elastomeric display element. This element has an uppermost transparent and solid plate which is made of glass or plastic resin material, serving as a solid base member of the element durable to outside mechanical stresses and shocks. The thickness may amount to about 0.2-2 mm, or so. Transparent upper electrodes are provided at the lower surface of the glass or plastic resin plate, these electrodes being shaped and arranged in registration with the display segments of a scheduled display pattern. The thickness may be in the order of 500-2,000 A.
