New constructions of RTN‐LCDs with antireflective (AR) coatings were proposed. Both one polarizer and Polarizer Beam Splitter (PBS) variants were considered. The AR coatings can be made both in the outer surface of the one‐polarizer RTN‐LCD and on the upper substrate between the glass plate and aligning layer. The damping of the LCD reflection in the “dark” state of one‐polarizer RLCD by introducing AR layers considerably improves the contrast ratio and only slightly affects the brightness of RLCD. The application of AR‐layers in PBS‐RLCD results in an improved brightness.
