Abstract

PURPOSE: To display various kinds of information with a less number of elements by reducing the IC ship size of a driving circuit by providing the function of two-layer liquid crystal display.
CONSTITUTION: This timepiece is equipped with time standard unit 2 including quartz vibrator 1, CPU3, decoders 5 and 6, input unit 4 for time correction, mode selection, memorandum input, etc., and dislay unit 7 in which two liquid crystal layers have been sealed. One liquid crystal layer of unit 7 displays seven days of the week with one element and the other liquid crystal layer is provided with at least seven element display parts. Then, six element display parts other than the current day of the week are put into operation to display the day of the week. As a result, day display and information display of sundays on the calendar, marks, etc., can be attained with a small number of elements.
