  The present invention relates generally to the field of liquid crystal display devices and more particularly to a liquid crystal display device operating in vertically aligned mode (VA-mode) in which liquid crystal molecules having a negative dielectric anisotropy are aligned generally perpendicularly to a panel surface of the liquid crystal display. A liquid crystal display according to the invention comprises a liquid crystal cell ( 6 ) of a vertical alignment mode, at least one polarizer ( 2, 10 ) arranged on each side of the liquid crystal cell, and at least one compensating structure ( 3, 7 ) disposed between the liquid crystal cell and at least one of the polarizers. The polarizers have transmission axes ( 11, 18 ) which are perpendicular to each other.

  This invention relates to polycyclic organic compounds of general structural formula (I): wherein Y is a predominantly planar polycyclic system being at least partially aromatic, W 1 , W 2 , and W 3 are different groups providing solubility in an organic solvent, and sum (n1+n2+n3) is 1, 2, 3, 4, 5, 6, 7 or 8. The polycyclic organic compounds are substantially transparent for electromagnetic radiation in the visible spectral range and are capable of forming supramolecules in the organic solvent.
