Title:
TRANSPARENT CONDUCTOR AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2014/196460
Kind Code:
A1
Abstract:
The present invention relates to a transparent conductor having a low surface electrical resistivity and high optical transparency, and also to a method for producing the same. Conventional ITO films pose problems in that sufficiently reducing surface electrical resistivity is difficult, and ITO films are not suited to uses that require flexibility because they have a tendency toward cracking. Therefore, thin films formed from Ag are being recommended as transparent conductor films, and transparent conductors and the like obtained by laminating a base layer formed from aluminum and an Ag layer are being recommended. Nevertheless, there is a need for a reduction in the visible-light average transmittance and a further increase in optical transparency. The present invention provides a transparent conductor that has both a high transparency and a low surface electrical resistivity as a result of a configuration comprising, in the following order, a transparent substrate, a base layer containing molybdenum and having a layer thickness of 2 nm or less, and a transparent metal film disposed adjacent to the base layer and having a film thickness of 15 nm or less.
