Optically compensated splay (OCS) mode, where the LCs are almost homeotropically aligned with a rubbed parallel at both surfaces, and where a mid-director orients itself parallel to the substrate, is known to show a wide-viewing-angle, due to self-compensation effect. Since a cell retardation value exists in the presence of an electric field, film compensation is necessary to realize a wide-viewing-angle and high contrast ratio. In this paper, we show various electro-optic characteristics, depending on cell configurations with optical compensation films.
