Abstract: A transparent conductive laminate for a semiconductor device includes a substrate, first and second refracting films, and a transparent conductive film formed on the second refracting film and having a pattern defined by etched and non-etched regions. The optical thicknesses of the first and second refracting films are controlled to reduce a difference between CIE b* color values produced in the etched and non-etched regions. The CIE b* color values are smaller than 1.15, and the differential value therebetween is less than 0.35 so that the pattern of the transparent conductive film can be obscured or hidden, thereby improving color homogeneity. A method of improving color homogeneity of the laminate is also disclosed.
