ABSTRACT:
The invention relates to an optical compensation element comprising a first transparent surface on which a transparent electrode is arranged; a second transparent surface on which a plurality of transparent main electrodes are arranged, several of which being respectively connected to control electrodes via a transverse electrode; and a material having a refractive index which changes according to the voltage applied, said material being arranged between the first and second transparent surfaces. The aim of the invention is to improve said compensation element. To this end, each main electrode is connected to a transverse electrode at a precise location.
