  • Publication number: 20150111048
    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.

  • Publication number: 20140186587
    Abstract: A transparent conductor including: a base layer, a first coating layer on the base layer and having conductivity, and a second coating layer on the first coating layer is disclosed. The base layer, the first coating layer and the second coating layer have refractive indexes of R1, R2 and R3, respectively, at a wavelength of 380 nm to 780 nm, and the transparent conductor has a difference between R1 and R2 (R1?R2) of about 0.05 to about 0.20, and a difference between R2 and R3 (R2?R3) of about 0.01 to about 0.20. An apparatus including the transparent conductor is also disclosed.
