This paper provides a complete physical picture of optical response time as a function of cell gap (d) in a wide voltage regime. Normally both rise and decay times are known to be proportional to d 2 in the small angle approximation (V-th < V < root 2V(th)), and in the high voltage regime where V pi < V < V-i the optical decay time is independent of d. In this paper, we found that between these two extremes there is a region where the response time is linearly proportional to d. Our analytical derivation is confirmed by experimental results.
