Abstract

The present invention relates to liquid-crystal (LC) media for use in LC displays of the PS (polymer stabilised) or PSA (polymer sustained alignment) type.

Description

technical field [0001] The invention relates to liquid crystal (FK) media for liquid crystal displays of the PS (polymer stabilized) or PSA (polymer stabilized alignment) type. Background technique [0002] Currently used liquid crystal displays (FK-displays) are generally those of the TN (twisted nematic) type. However, they have the drawback of strong viewing angle dependence of contrast. In addition, so-called VA (Vertical Alignment) displays with wider viewing angles are known. The liquid-crystal cell of a VA display contains a layer of a liquid-crystal medium between two transparent electrodes, the liquid-crystal medium generally having a negative dielectric (DK) anisotropy value. In the de-energized state, the molecules of the liquid crystal layer are aligned perpendicular to the electrode plane (homeotropic) or tilted homeotropically (English “tilted”). When a voltage is applied to the electrodes, a reorientation of the liquid crystal molecules parallel to the face...
