Abstract
A liquid crystal calendar display device presents a full month of dates in a large-sized format. Sunday is always located in the left column or in the alternative in the right column of the calendar display regardless of the day which is the first date in the presented month. Only 16 electrode patterns are used to form all dates, and months of twenty-eight to thirty-one days are accommodated. Display elements are driven by a V-2V AC amplitude selective multiplexed system.
