<p>A touch sensitive device having a dielectric layer between a cover layer and a touch sensor layer is disclosed. The dielectric layer can reduce a negative pixel effect associated with poor grounding of an object touching the device. The dielectric layer can reduce a capacitance per unit area of the device to less than about 0.0305 picofarads per square millimeter, thereby reducing the negative pixel effect. The dielectric layer can have a thickness of about 0.50 millimeters or more and/or a dielectric constant of about 2.3 or less to reduce the negative pixel effect.</p>
