1. A touch sensor electrode, comprising:

  • a transparent dielectric substrate having a first surface and a second surface opposite to the first surface,a plurality of first electrodes arrayed in a first direction on the first surface and each extending along a second direction perpendicular to the first direction; and

    a plurality of second electrodes arrayed in the second direction on the second surface and each extending along the first direction,wherein each one of the first electrodes and each one of the second electrodes include a plurality of reference pattern elements,each of the reference pattern elements has a main line and a sub-line and forms a pattern with reference to a reference direction, which is the first direction for the first electrodes and the second direction for the second electrodes, respectively,the main line extends linearly from a first main endpoint to a second main endpoint in a main line direction that forms an angle in a range of from 58°

    to 68°

    relative to the reference direction,the sub-line extends linearly from the second main endpoint to a sub-endpoint in a direction perpendicular to the main line and has a length half of the main line, where the sub-endpoint is the first main endpoint of another reference pattern element located in the main line direction with relative to the sub-line, andthe first and second electrodes are formed such that the reference pattern elements of the first and second electrodes together form a lattice pattern in plan view perpendicular to the transparent dielectric substrate, and that the lattice pattern include a plurality of lattice units each in a square shape where each side has a same length as the sub-line.
