ABSTRACT:
A liquid crystal display adapted for a solid state analog timepiece has front and rear transparent substrates with radial transparent electrodes to represent hour, minute and second hands. The contact terminals connected to the electrodes are grouped in an array at the center of the front substrate. An elastomeric connector containing multiple discrete conductors extends through a center hole in the rear substrate to connect the array of contact terminals on the front substrate with a similar array of contact terminals on a printed circuit board behind the display. Liquid crystal material is sealed between the substrates both at the periphery of the display and around the central hole.
