Display device

摘要

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.

1. A display device comprising:
a display panel comprising:
a plurality of pixels, each having a pixel electrode; anda common electrode;a transparent conductive film disposed at a surface on a viewer side of the display panel for noise shielding; and a voltage generation unit configured to supply a voltage having an AC component superposed on a DC component to said transparent conductive film, wherein the AC component supplied to the transparent conductive film comprises a voltage with a reverse polarity with respect to a spike-shaped voltage occurring at the common electrode, and wherein the AC component supplied to the transparent conductive film has a waveform which is a reverse phase to the spike-shaped voltage occurring at the common electrode.
