ELECTRICALLY CONDUCTIVE SUPPORT FOR A GLAZING UNIT HAVING LIQUID-CRYSTAL-MEDIATETD VARIABLE SCATTERING PROPERTIES AND SUCH A GLAZING UNIT

摘要

The present invention relates to an electrically conductive carrier for a liquid-crystal glazing unit (100) comprising a multilayer (3) containing, in this order: an electrode comprising an electrically conductive transparent oxide based layer, called the TCO layer; a first barrier layer, based on silicon nitride, of thickness e1 of at least 5 nm; and a second barrier layer, based on silicon oxide, of 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 layers is larger than or equal to 50 nm and smaller than 150 nm.
