Fluorine in liquid crystal design for display applications

Fluorine is an essential component of most liquid crystalline materials as they are used in LCD devices. The reasons for this are manifold: fluorination limits the coordination ability to cationic impurities and thus improves reliability of the LCD, it provides a custom-tailored molecular dipole moment with the right orientation, and it can stabilize certain conformations and rigidify flexible alkyl chains.
