A proposal on and verification of surface alignment of liquid crystals aligned by frictional rubbing

The alignment of liquid crystals on a treated surface has been qualitatively explained by introducing the concept of a hot spot. The coherent length of liquid crystals and the density of hot spot are important factors governing the stability of alignment. This proposal of hot spot was verified exper...

Beschreibung
Zusammenfassung:	The alignment of liquid crystals on a treated surface has been qualitatively explained by introducing the concept of a hot spot. The coherent length of liquid crystals and the density of hot spot are important factors governing the stability of alignment. This proposal of hot spot was verified experimentally. A method to obtain good alignment is also proposed.
