Variation of tilt angle on surface of alignment layer under electric field was investigated by reflection measurement in thin (2–5 μm) twisted LC cell. Dependence of tilt angle from voltage was used for determination of polar anchoring properties of two alignment materials with different polar anchoring energy. It introduces the new method for investigation of polar anchoring properties of nematic liquid crystal cell, which has twisted structure and small cell gap.
