Abstract

PURPOSE: To avoid the disturbance of screen due to large sized unit, by changing the set position of the common electrode terminal, according to the voltage fed to the drive electrode and the voltage to be fed to the common electrode of liquid crysstal cells.
CONSTITUTION: The common electrode terminal 8 for the liquid crystal display unit of matrix type is provided according to the common electrode voltage and the drive voltage. That is, taking the substrate bias voltage of silicon chip as Vo, the potential of the common electrode terminal 8 as Vc, and the voltage driving the liquid crystal fed from the serial conversion circuit 7 to the X electrode as VD, if |VD|>|VC|, the drawing terminal 24 is placed at the location of the common electrode 12 apart from the scanning circuit 6 and serial parallel conversion circuit 7. Further, if |VO|<|VC|, the drawing terminal is provided at the location of the common electrode 12 near the scanning circuit 6 and the serial parallel conversion circuit 7. Thus, since the location of the common terminals 24 and 25 can be determined according to the common electrode voltage and the drive voltage, even with large sized display unit, the disturbance due to long sized electrode can be avoided.
