ABSTRACT:
The invention relates to an optical compensator for liquid crystal displays comprising: at least one O plate retarder (3, 3′), and at least one twisted A plate retarder (6, 6′) with a twist angle φ of more than 90°, and further relates to a liquid crystal display comprising such a compensator, a liquid crystal cell (1) and polarizers (2, 2′).
