Abstract
A liquid crystal display device is disclosed which possesses many of the advantages of a dot matrix type of display, with respect to flexibility of changing character or symbol position and size, together with the advantages of a limited number of external connecting leads provided by a segment type of display which can indicate only numerals or symbols of predetermined size at predetermined locations. The display device is based upon a matrix of groups of display segments, with each group or the segments within a group being individually selectable to form numerals and characters using either individual display segments or combinations of groups of display segments.
