Abstract
A transparent conductive layer is made of a graphene transparent conductive material and is in the form of a thin film having a thickness of 0.36 nm-10 nm, transmittance of visible light being 80-97%, and surface resistance being 30-500Ω/□. A CF substrate includes the graphene transparent conductive layer to replace and ITO transparent conductive layer in order to obtain an electrode or a static electricity draining layer having high transmittance and excellent flexibility and, when used in a liquid crystal display panel, helps improve the transmittance of the liquid crystal panel and reduce the use of backlighting. Also provided is a manufacturing method of the CF substrate having the graphene transparent conductive layer, which uses a CVD process to form graphene on a growth substrate to be subsequently transferred to a CF substrate body.
