Abstract

PURPOSE:To cause easy-to-see and mechanical analog type liquid crystal display to be accomplished by displaying the hour, minute and second in respectively different shapes or hues simultaneously on a concentric circle or the like. CONSTITUTION:Time-reading split graduations are provided on the outside top surface of a liquid crystal display body or the peripheral part in proximity thereto. transparent electrodes are provided on the top and bottom surfaces on the inner side of the plates sandwiching the liquid crystal layer, the one surface being provided respectively one or more common electrods for the hour, minute and second and the other surface with a multiplicity of segement electrodes disposed radially. This watch displays analogically the hour, minute and second by these segment electrodes, wherein the displaying is accomplished simultaneously by providing respectively different shapes or hues to the hour display 15, minute display 16 and second display 17 on the concentric circle. In the figure is shown 10 o'clock 12 minutes 35 seconds.
