In LCDs various LC modes of operation are applied like twisted nematic (TN) [5], super twisted nematic (STN)[6], vertically aligned nematic (VAN) [7,8], optically compensated birefringence (OCB) [9] and in plane switching (IPS) [10-12]. The LC mode used depends on the demands of a specific application, like the viewing angle, power consumption and manufacturing cost.

The generation of high pretilt angle by such an approach led immediately to the development of vertically aligned nematic (VA)-LCDs using PI films with a very high pretilt angle of 89° on the basis of the research of Pl-coated STN-LCDs. 

In the vertically aligned mode (VA mode), the long axis of rodlike hquid crystal molecules is oriented perpendicular to the glass substrate. In general, nematic liquid crystals with a negative anisotropy of the dielectric constant are used.
