Abstract

A liquid crystal display having a liquid crystal cell (1) has electrical heating formed by an electrically conductive heating layer (3) on a substrate (2). On opposite sides, a clamp (4) forming a busbar in each case reaches over the substrate (2) and bears on the heating layer (3) by a limb (5). For connection to the heating current source, a spring element (7) is arranged between a limb (6) of the clamp (4) and a printed circuit board (8).
