The reaction of liquid crystal to electric field in vertical-alignment (VA) mode has been studied in this work. A series of experiments with the concave-convex boundary conditions are designed to investigate the effect of fringe field in polymer sustained alignment (PSA) mode. According to the experimental results, we propose a new mechanism of LC alignment named Topography Induced Self-Alignment (TISA). Owing to the TISA mechanism, the transmissive property of VA-LCD pixel has less independence on process variation than the pixel with conventional polymer sustained alignment.
