Conductive support for a glazing unit having liquid crystal mediated variable scattering properties and the glazing unit

摘要

The invention comprises an electrode comprising a layer based on a conductive transparent oxide called a TCO layer, a first barrier layer having a thickness e1 of at least 5 nm based on silicon nitride, and a thickness e2 based on silicon oxide. Comprising a multilayer (3) in this order with a second barrier layer of at least 30 nm, the thickness e1 being less than e2 and / or e1 being less than 80 nm, wherein the first and second barrier layers The present invention relates to a conductive support for a liquid crystal glazing unit (100) having a cumulative thickness eb of 50 nm or more and less than 150 nm.
