1. A conductive sheet, comprising:
a transparent substrate; and
a first conductive pattern on a surface of the transparent substrate, the first conductive pattern including a plurality of first thin metal wires extending in a first direction and a plurality of second thin metal wires extending in a second direction, the plurality of second thin metal wires intersecting with the plurality of first thin metal wires, to form a plurality of first intersections, each first intersection forming a first obtuse angle,
the first conductive pattern further including a plurality of first bent wires, at least one first bent wire connecting at least one first thin metal wire and at least one second thin metal wire, the first thin metal wire, the first bent wire, and the second metal wire forming a first connection, the first connection comprising a first pair of two obtuse angles, and
at least one of the plurality of first bent wires connecting two facing first obtuse angles formed by two of the plurality of first intersections,
each of the plurality of first thin metal wires and
each of the plurality of second thin metal wires
having a same length of 300 μm to 1300 μm, and
each of the plurality of first bent wires being parallel to at least one other of the plurality of first bent wires and each of the first bent wires having a length of 8 μm to 20 μm,
the plurality of first thin metal wires, the plurality of second thin metal wires, and the plurality of first bent wires comprising a mesh comprising first openings, at least a plurality of the first openings (i) having the same shape as one another and (ii) being arranged consecutively in the first direction and the second direction.
