ELECTRICALLY CONDUCTIVE CARRIER FOR A GLAZING UNIT WITH VARIABLE LIQUID-CRYSTAL-INDUCED SCATTERING, AND SUCH A GLAZING UNIT

摘要

The present invention relates to an electrically conductive support for a liquid-crystal-comprising glazing unit (100), comprising a multilayer (3) with, in this order: an electrode comprising a film, called the TCO film, based on transparent electrically conductive oxide; a silicon-nitride-based first barrier film having a thickness e1 of at least 5 nm; and a silicon-oxide-based second barrier film having a thickness e2 of at least 30 nm; the thickness e1 is smaller than or equal to e2 and/or e1 is smaller than 80 nm, and the cumulative thickness eb of the first and second barrier films is larger than or equal to 50 nm and smaller than 150 nm.
