Abstract

A position detecting sensor includes a grid structure composed of plural electrodes extending in a first direction and plural electrodes extending in a second direction perpendicular to the first direction. The electrodes have light permeability. In a rectangular area defined by four cross-points, where two adjacent electrodes extending in the first direction and two adjacent electrodes extending in the second direction cross each other, a dummy pattern is disposed so as to provide uniform optical characteristics for the sensor. At least some of the electrodes extending in the first direction are shaped to include inclinations relative to the first direction, so as to minimize the Moire effect that may develop between the electrodes and an array of pixels in an overlaid display device. Also, at least some of the electrodes extending in the first direction are shaped to be line-symmetric about a straight line extending in the first direction.
