What was discovered

Discovery of the twisted nematic structure of liquid crystals, in which molecules form a helical twist between two surfaces; decades later this property became the basis of liquid crystal displays (LCD).

The twisted-nematic effect that revolutionized displays is usually credited to Schadt, Helfrich, and Fergason (1970-1971); this entry corresponds to Mauguin's original 1911 discovery of the twisted structure that made it possible.

What it led to

  • liquid crystal displays (LCD)
  • low-power digital watches and calculators
  • flat-panel displays that displaced CRTs
  • portable electronics with screens
