Abstract
The electro-optical glare protection filter includes a liquid crystal cell, which is a laterally extended liquid crystal cell defining a volume between two laterally extended sides. The volume containing liquid crystals and having, in a vertical direction perpendicular to lateral directions, a thickness being smaller than an extension of the volume in any lateral direction. The FFS cell includes a first electrode structure and a second electrode structure, which are arranged to change an orientation of the liquid crystals in the volume when a voltage is applied between them. Both the first and the second electrode structure are present at the same laterally extended side of the volume. The first electrode structure may include a plurality of electrically separate electrodes, and the second electrode structure may include a plurality of electrode lines.
