Thin retardation layers are developed. The thin films can be applied in‐ or outside the LCD cell by wet coating techniques. The cell thickness can be reduced considerably since carrier sheets, protective layers and adhesive layers are no longer a necessity. In addition, the optical properties can be patterned on subpixel level which improves the LCD on grey scale inversion, contrast and/or brightness depending on the display type. Photoalignment and thickness patterning are presented as technologies towards patterned optical foils.
