Packaging on Surface Orientation

In the section on packaging we have indicated that some liquid crystals are adversely affected by coming in contact with moisture consequently, for these materials a good water-tight seal is necessary. The moisture can increase the fluid conductivity, produce a lowering of the mesomorphic-isotropic transition, or can participate in the production of impurities in the fluid that are adsorbed onto the surface 

A short outline of the standard conductive coatings and packaging methods has been presented. 

Finally, two examples have been presented which show the relationship between packaging techniques and liquid-crystal molecular orientation.
