Abstract
A position detecting device includes: a display unit having a first electrode formed of a transparent conductive film, a plurality of second electrodes, and display material interposed between the first electrode and the second electrodes; a display driver configured to drive the display unit based on a video signal input to the display driver; and a position detecting section configured to detect a position of an indicator on the first electrode and to output the detected position. The display unit may comprise, for example, an 'electronic paper,' such that the display state of the display unit can be maintained even after a drive power applied between the first electrode and the second electrodes is discontinued.
