Problems solved by technology

[0008] In the second mode, the display device is turned off to form a black screen, and when viewed under external light such as fluorescent lamps, sunlight, and LED light, it is difficult to visually recognize thin metal wires
[0009] In the structure described in Japanese Patent Application Laid-Open No. 2008-282924, since the metal layer is formed at the intersection to increase the area of ​​the intersection, the intersection of the grid tends to be conspicuous, which is disadvantageous in terms of visibility.
In the structure described in Japanese Patent Laid-Open No. 2008-306177, since a metal layer is formed in the opening, the aperture ratio decreases and the transparency may decrease.

Embodiment 1

[0174] Hereinafter, the present invention will be described more specifically with reference to examples of the present invention. In addition, materials, usage amounts, ratios, processing contents, processing procedures, and the like shown in the following examples can be appropriately changed as long as they do not depart from the spirit of the present invention. Therefore, the scope of the present invention should not be limitedly interpreted by the specific examples shown below.

no. 1 Embodiment

[0176] In the first example, in Examples 1 to 11, the line width of the thin metal wires and the length of one side of the lattice were changed, and the visibility, aperture ratio, and streaks of the conductive film were evaluated. The detailed items and evaluation results of Examples 1 to 11 are shown in Table 3 to be described later.

[0177] (Example 1)

[0178] (Silver halide photosensitive material)

[0179] An emulsion containing silver iodobromochloride particles (I=0.2 mol%, Br=40 mol%) with an average spherical equivalent diameter of 0.1 μm and 10.0 g of gelatin with respect to 150 g of Ag in an aqueous medium was prepared.

[0180] In addition, adding K to this emulsion 3 Rh 2 Br 9 and K 2 IrCl 6 so that the concentration becomes 10 －7 (mol / mol silver), Rh ions and Ir ions are doped in silver bromide particles. Add Na to this emulsion 2 PdCl 4 , and then use chloroauric acid and sodium thiosulfate to carry out gold-sulfur sensitization, and then apply it to...

Embodiment 2

[0192] In Example 2, except that the length La of one side of the grid 24 was 400 μm and the length Lb of the streak suppressing portion 26 was 100.0 μm, the conductive film of Example 2 was produced in the same manner as in the above-mentioned Example 1.

Abstract

A conductive film (10) is a conductive film that has a conductive portion (14) configured with thin metal wires (16) and apertures (18), wherein the conductive portion (14) has points of intersection (22) by the plurality of the thin metal wires (16), and at portions that are over the thin metal wires (16) and that are other than the points of intersection (22), moiré suppression units (26) (projecting portions) are disposed. It is preferable that the moiré suppression units (26) be randomly disposed.

Description

technical field [0001] The present invention relates to a conductive film capable of suppressing the generation of moire. Background technique [0002] Recently, a conductive film used in a touch panel has attracted attention as a conductive film provided in a display device. The touch panel is mainly applied to a small size such as a PDA (portable information terminal) or a mobile phone, but it is also conceivable that the touch panel will lead to an increase in size through application to a computer display or the like. [0003] In such future trends, the conventional electrodes use ITO (indium tin oxide), so the resistance is high, and as the application size becomes larger, the transmission speed of the current between the electrodes becomes slower, and the response speed (from contact with the fingertip) The problem of slowing down the time to detect the position). [0004] Therefore, it is conceivable to reduce the surface resistance by arranging a large number of la...
