Abstract Very thin quarter lambda plate was fabricated using liquid crystal polymer, aiming to use for parallax free high contrast G‐H reflective displays. UV curable LC polymer was aligned by either by rubbed polyimide or UV alignment process. The film was thin enough by optimization of monomer composition, so that the voltage loss was small enough when the film is placed between two electrodes inside cell. Contrast ratio of the G‐H cell using this film was almost comparable to that using commercially available dispersion compensated multiplayer film.
