An electrically conductive support for a glazing unit having liquid crystal scattering properties may include a multilayer of thin films. In one example, the thin films include an electrode comprising a TCO film, 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 may be smaller than or equal to e2 and/or smaller than 80 nm. Further, the cumulative thickness of the first and second barrier films may be larger than or equal to 50 nm and smaller than 150 nm.
