    摘要: A glare protection filter, in particular for a welding mask or welding protection device including an electro-optical light filter 10 that includes at least one electro-optical cell (12, 13, 14, 15, 16, 17, 18) by which an amount of light transmitted through the filter is reducible, wherein at least a first one of the electro-optical cells comprises two parallel transparent plates (12, 18) having transparent electrodes (13, 17) on the inner surfaces thereof and containing a liquid crystal material (15) and orientation layers (14, 16) defining an anchoring of the liquid crystal material (15). Upon application of a voltage of less than 30V to the electrodes (13, 17), the molecule orientation in the liquid crystal material (15) near at least one of the orientation layers (14, 16) is subject to rotation of at least 10°.
