CONDUCTIVE MATERIAL, POLARIZER USING THE SAME, CIRCULAR POLARIZATION PLATE, INPUT DEVICE AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a conductive material having a small extinction ratio by suppressing orientation and aggregation of a metal nanowire, and to provide a polarizer, a circular polarization plate, an input device and a display device using the same.SOLUTION: The conductive material includes a substrate, and a conductive layer including at least a metal nanowire having an average short axis length of 5-30 nm on the substrate. The dry film thickness of the conductive layer is 0.001-0.1 time of the average long axis length of the metal nanowire. The conductive material is obtained by coating the substrate with a conductive coating liquid, containing at least a metal nanowire having an average short axis length of 5-30 nm and a matrix component, so that the wet film thickness of the conductive layer is 0.2-20 times of the average long axis length of the metal nanowire.
