Abstract

A transparent glazing unit including a resistive heating coating that extends over a substantial part of the glazing unit, in particular over a main viewing field, and is electrically connected to at least two busbars such that, when an electrical supply voltage is applied between the busbars, a current flows, which heats a heating field in the coating. The heating field includes at least one semiresistive region in direct contact with at least one busbar.
