Abstract
A display device is provided which includes a display panel having pixels, each pixel having a pixel electrode, a common electrode, an image line to supply an image signal to the plurality of pixels, and a transparent conductive film disposed at a surface on a viewer side. The display device display panel, also includes a voltage generation unit to supply a voltage having an AC component superposed on a DC component to the transparent conductive film. The AC component is a voltage with reverse polarity with respect to a spike-shaped voltage occurring at the transparent conductive film to thereby cancel out effects of the spike-shaped voltage on the transparent conductive film.
