  • Patent number: 10115495
    Abstract: A transparent conductor includes a base layer, and a conductive layer on an upper surface of the base layer. The conductive layer includes metal nanowires and a matrix. The transparent conductor has a reflective a* value of about ?0.3 to about +0.3 and a reflective b* value of about ?2 to about 0. The transparent conductor exhibits good optical properties and prevents (or reduces) visibility of the etching pattern of the conductive layer.
