Abstract
A new electric-field-induced color range, in which colors change from blue to red with increasing field, has been observed in cholesteric liquid crystals. Observations of this new color range quantitatively confirm the theories of Meyer and de Gennes and enable identification of the specific nature of the electric-field-induced cholesteric-nematic phase transitions previously observed by other workers.Keywords
