Abstract
A first planar input unit includes a transparent first substrate and a transparent second substrate that are stacked on each other. On an electrode formation surface of the first substrate, transparent Y-driving electrodes and transparent shielding layers are formed. On an electrode formation surface of the second substrate, X-driving electrodes and first detection electrodes are formed. At the rear of the first substrate, a display unit, such as a liquid crystal panel, is provided. Since the shielding layers are located between the display unit and the first detection electrodes, a change in the potential of the first detection electrodes is prevented from being adversely affected by noise emitted from the display unit.
