Abstract
The alignment of liquid crystals on a treated surface has been qualita tively explained by introducing the concept of a hot spot. The coheren t length of liquid crystals and the density of hot spot are important factors governing the stability of alignment. This proposal of hot spo t was verified experimentally. A method to obtain good alignment is al so proposed.
