ABSTRACT:
A common electrode driving circuit for use in a display apparatus including a first substrate; a second substrate opposed to the first substrate with a display medium interposed therebetween; a plurality of pixel electrodes, a plurality of common electrode driving terminals provided on a surface of the first substrate opposed to the second substrate; and at least one common electrode provided on a surface of the second substrate opposed to the first substrate. The common electrode is opposed to the plurality of pixel electrodes and is connected to the plurality of common electrode driving terminals respectively through a plurality of common electrode transfer resistances. The common electrode driving circuit includes a detection device for detecting a resultant voltage applied to the common electrode through at least one of the plurality of common electrode transfer resistances; and a driving voltage generating circuit for generating a driving voltage based on a reference signal and a resultant voltage applied to the common electrode which is detected by the detection device and outputting the driving voltage to the plurality of common electrode driving terminals.
