Abstract
The Kerr effect depends very strongly on the temperature and is associated with high operating voltages. The present invention relates to an electrically controllable optical element which comprises a cell (D) filled with a starting mixture (K) and having two substrates () and a conductive layer () applied onto the inner surface of the respective substrate (), wherein the starting mixture (K) comprises a mixture of dipolar, rod-shaped molecules () and semi-mesogenes () as active constituents, and wherein the starting mixture (K) forms a thin layer having a wide-meshed, anisotropic network () produced by photo-polymerization between the structured or/and flat conductive layers (), which are applied onto a substrate (), in a thin-film cell (D). According to the invention, an optically active surface profile (O) is incorporated on the inner surface of a substrate (or) or into the substrate (or) or both substrates (and).
