Abstract
A film type compensation cell for an LCD which compensates for the twist angle of the liquid crystal in the LCD. The compensation cell has two compensation films, having orientation grooves formed on the surfaces thereof. Liquid crystal is between the two compensation films and is twisted in an opposite direction of the liquid crystal in the LCD. Compensation cells can be manufactured by forming orientation grooves on the surfaces of the compensation films and applying a liquid crystal therebetween. The compensation films are then pressed together and cut to the requisite size.
