ABSTRACT:
A wiring 19 of a device directly detects a voltage from a plurality of scanning electrodes 1, a voltage detecting electrode 701 detects a voltage from a plurality of the scanning electrodes 1. A voltage variation component such as voltage distortion of the detected voltage which adversely affects on an image display is taken out, inverted, and negative fed back to the scanning electrode 1. A negative feedback loop provides the negative feedback of the voltage detected from and fed back to the scanning electrode 1, this therefore suppresses the disadvantageous voltage variation such as a distortion voltage which tends to arise in the scanning electrode 1.
