11. Twisted nematic liquid crystal displays were superior to the earlier dynamic scattering displays, and soon became widespread. 12. The nematic phase is of the type I, and the aggregates have a positive and diamagnetic anisotropy. 13. The change of phase at the lamellar-nematic temperature has been ascribed to order-disorder transitions. 14. The team then proceeded to prepare numerous mixtures of nematic compounds many of which had much lower melting points. 15. Thus, they adopt ordered structures in the molten phase, e . g . smectic and nematic phases. 16. For a perfect nematic \ psi = 0 and for a smectic phase \ psi will take on complex values. 17. The discotic nematic phase includes nematic liquid crystals composed of flat-shaped discotic molecules without long-range order. 18. The discotic nematic phase includes nematic liquid crystals composed of flat-shaped discotic molecules without long-range order. 19. The twisted nematic phase has the molecules oriented in layers with regularly changing orientation, which gives them periodic spacing. 20. Other phases, such as nonpolar nematic , polar nematic, stringbean, donut and onion phases, have been predicted.
