Abstract
The present invention pertains to: a conductive sheet, a touch panel, a display device, a method for producing the conductive sheet, and a recording medium. In the present invention, the relative refractive index of a substrate with respect to a first protective layer, and/or the relative refractive index of the substrate with respect to a second protective layer is 0.86-1.15. The relative refractive index of a first substrate with respect to the first protective layer, and/or the relative refractive index of a second substrate with respect to the second protective layer is 0.86-1.15.

A conductive sheet comprising:
- a substrate;
- a first conductive portion made up from a plurality of thin metal wires and which is formed on one main surface of the substrate;
- a first protective layer disposed on the one main surface in covering relation to the first conductive portion;
- a second conductive portion made up from a plurality of thin metal wires and which is formed on another main surface of the substrate;
- and
- a second protective layer disposed on the other main surface in covering relation to the second conductive portion,
- wherein at least one of a relative index of refraction of the substrate with respect to the first protective layer and a relative index of refraction of the substrate with respect to the second protective layer is 0.86 to 1.15.
A conductive sheet comprising:
- a first substrate;
- a first conductive portion made up from a plurality of thin metal wires and which is formed on one main surface of the first substrate;
- a first protective layer disposed on the one main surface of the first substrate in covering relation to the first conductive portion;
- a second substrate;
- a second conductive portion made up from a plurality of thin metal wires and which is formed on one main surface of the second substrate;
- and
- a second protective layer disposed on the one main surface of the second substrate in covering relation to the second conductive portion,
- wherein at least one of a relative index of refraction of the first substrate with respect to the first protective layer and a relative index of refraction of the second substrate with respect to the second protective layer is 0.86 to 1.15.
A method for producing a conductive sheet comprising:
- a selection step of selecting plural positions from within a predetermined two-dimensional image region;
- a generation step of generating image data that represent a pattern of a mesh pattern based on the selected plural positions;
- a calculation step of calculating a quantified evaluation value concerning noise characteristics of the mesh pattern, based on the generated image data;
- a determination step of determining one of the image data as output image data, based on the calculated evaluation value and predetermined evaluation conditions;
- an image cutting out step of cutting out first image data representing a pattern on one main surface side of a substrate, and second image data representing a pattern on another main surface side of the substrate, from the determined output image data;
- and
- an outputting step of obtaining the conductive sheet, on which the mesh pattern is formed on the substrate as viewed in plan, by output formation of a wire material on the one main surface side of the substrate based on the cut out first image data, and by output formation of the wire material on the other main surface side of the substrate based on the cut out second image data.
A non-transitory recording medium storing a program therein for producing image data that outputs and forms a wire material on a substrate, the program enabling a computer to function as:
- a position selecting unit for selecting plural positions from within a predetermined two-dimensional image region;
- an image data generating unit for generating image data that represent a pattern of a mesh pattern based on the plural positions selected by the position selecting unit;
- an evaluation value calculating unit for calculating a quantified evaluation value concerning noise characteristics of the mesh pattern, based on the image data that is generated by the image data generating unit;
- a data determining unit for determining one of the image data as output image data, based on the evaluation value calculated by the evaluation value calculating unit and predetermined evaluation conditions;
- and
- an image cutout unit for cutting out first image data representing a pattern on one main surface side of the substrate and second image data representing a pattern on another main surface side of the substrate, from the output image data determined by the data determining unit.
