Beschreibung
Zusammenfassung:	A liquid crystal display device includes a liquid crystal layer, a common electrode, and an electrode set. The liquid crystal layer is placed between said common electrode and the electrode set, and the electrode set is provided for switching the liquid crystal layer. The electrode set includes a first electrode for switching a first area of the liquid crystal layer and a second electrode for switching a second area of the liquid crystal layer. Particularly, the second area includes at least a part of the area of the liquid crystal layer that the first area does not include. The first electrode has a shape which in cooperation with the second electrode allows alignment of the LC molecules in substantially two orthogonal directions. A method is provided to get rid of the circular polarizers which provide a good on-axis aperture ratio but which show reduced off-axis performance compared to linear polarizers.
