Abstract
PURPOSE: To increase rows of picture elements without increasing the number of common electrodes by providing an extended portion at the specified section of common electrode and changing the segment electrode to dot segment.
CONSTITUTION: In case of the opposing type electrode in matrix structure, common electrode 11 is, for example, divided into three electrode patterns 11a, 11b and 11c connected to three electrode lines COM1, COM2 and COM3 and each pattern is arranged in the lateral direction while extended portion 12 is formed at the required section in the longitudinal direction, thus playing essentially the role of 4 electrode patterns. Segment electrode 13 is formed by arranging dot segment 14 of 4 and 6 rows and eight segment electrode lines SG1WSG8 are provided from 6 rows so that the wirings of two dot segments 14 corresponding to the extended portion 12 of common electrode 11 are not doubled. When displaying a letter T by menas of multiplex drive, picture elements b and d can be lighted by applying +V signal voltage to one electrode line COM1 and -V signal voltage to segment electrode lines SG3 and SG4.
