Title:
CONDUCTIVE SHEET, TOUCH PANEL, DISPLAY DEVICE, AND METHOD AND PROGRAM FOR PRODUCING CONDUCTIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2013/051548
Kind Code:
A1
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.
