Electroconductive sheet and touch panel

摘要

An electroconductive sheet and a touch panel having a first electroconductive section and a second electroconductive section, the second electroconductive section being disposed on the display-panel side. The first electroconductive section has a plurality of first electroconductive patterns arranged in the x-direction, a plurality of first large grids being respectively connected to the first electroconductive patterns. The second electroconductive section has a plurality of second electroconductive patterns arranged in the y-direction, a plurality of second large grids being respectively connected to the second electroconductive patterns. The area occupied by thin metal wires in the second electroconductive patterns is larger than the area occupied by thin metal wires in the first electroconductive patterns. The area occupied by thin metal wires in the second large grids is larger than the area occupied by thin metal wires in the first large grids.
