1. A display device comprising:
a substrate; a plurality of pixel electrodes arranged in a matrix in a plane parallel with said substrate; a display functional layer configured to display an image as a result of an image signal supplied to said plurality of pixel electrodes; a driving electrode opposed to said plurality of pixel electrodes; and a plurality of detecting electrodes arranged in a plane opposed to said driving electrode, each detecting electrode extending in a first direction of the matrix and each having a predetermined width in a second direction of the matrix, the first direction being perpendicular to the second direction, and said detecting electrodes being arranged in parallel to each other with a predetermined pitch, wherein,
each of the plurality of detecting electrodes is connected to a detecting circuit through a wire across an end of the plane in the first direction of the matrix,the predetermined width and the predetermined pitch of each detecting electrode correspond to a multiple other than 1 of the pixel pitch, where the predetermined width and pixel pitch are the same or different,the plurality of pixel electrodes arranged such that a direction in which pixel electrodes of the same color are located adjacent to one another is aligned with the first direction, the predetermined widths of the detecting electrodes correlate with pixel size and pixel pitch, and the detecting electrodes are arranged to overlay only pixels having the same color.
