[0416]

[0417] (Silver halide photosensitive material)

[0418] An emulsion containing silver chlorobromoiodide grains (I = 0.2 mol%, Br = 40 mol%) having an average spherical equivalent diameter of 0.1 micron was prepared. The emulsion contained 10.0 grams of gelatin in an aqueous medium relative to 150 grams of Ag.

[0419] Will K 3 Rh 2 Br 9 and K 2 IrCl 6 added to the emulsion so that the concentration becomes 10 -7(mol / mol Ag) to dope Rh ions and Ir ions into silver bromide grains. Na 2 PdCl 4 Added to the emulsion, and additionally, the emulsion was gold sulfur sensitized using chloroauric acid and sodium thiosulfate. Subsequently, the emulsion is coated on a transparent substrate (here, polyethylene terephthalate (PET) having a refractive index of n0=1.64) together with a gelatin hardener, so that the coated amount of silver becomes 10 g / m2. In this case, the Ag / gelatin volume ratio was set to 2 / 1.

[0420] The emulsion was coated onto a PET support with ...

Abstract

In conductive sheets (10, 11), a mesh pattern (20) in which different mesh forms (22) are arranged in planar view is formed by means of conductive parts (14a, 14b) which are formed on at least one main surface of a base (12) and which are formed from multiple metal thin wires (16), wherein the mesh pattern (20) is formed such that, with regard to the power spectrum (Spcc) of the center position of each mesh form (22) in a two-dimensional distribution, the average strength (PH) towards the spatial frequency bandwidth that is higher than a predetermined spatial frequency (Fb) is greater than the average strength (PL) towards the spatial frequency bandwidth that is lower than the predetermined frequency (Fb). As a result, it is possible to reduce the noise / granular feeling caused by the pattern and to dramatically improve the visibility of an object to be observed in said conductive sheets (10, 11). The touch panel and display device of the present invention contain said conductive sheet.

Description

technical field [0001] The present invention relates to a conductive sheet, a touch panel, and a display device including the conductive sheet, a method for manufacturing the conductive sheet, and a recording medium on which a program is recorded. Background technique [0002] In recent years, electronic devices including touch panels have been widely used. The touch panel is mounted on various devices including a small-sized screen, such as a mobile phone or a personal digital assistant (PDA). In the future, installation of touch panels in devices including large-sized screens such as monitors for personal computers (PCs) is highly anticipated. [0003] As a conventional touch panel electrode, indium tin oxide (ITO) is mainly used in terms of optical transparency. It is known that the resistance per unit area of ​​ITO is relatively high compared with metals and the like. That is, in the case of ITO, as the screen size (total area of ​​the touch panel) increases, the shee...
