Abstract
The present invention relates to a conducting substrate and a touch screen comprising the same, and the conducting substrate according to the present invention comprises a board, an electric conducting pattern provided on at least one surface of the board, and a darkening layer provided on at least one surface of the electric conducting pattern and in a region corresponding to the electric conducting pattern, wherein a reflective diffraction intensity of a reflective diffraction image obtained by radiating light emitted from a point light source on one surface from which the darkening layer is visible is reduced by 60% or more as compared to the conducting substrate having the same constitution except that the electric conducting pattern is formed of Al and does not comprise the darkening layer.
