Optical properties of thin liquid crystal cells are found to deviate significantly from those of thick cells. Results on the liquid crystal thickness dependent phase retardation, effective birefringence, and decay time of thin E-7 cells are presented. A simple model which is based on the partially disordered surface layers is developed to explain the observed phenomena. The concept of virtually inactive surface layers is introduced.
