The VATN(Vertically Aligned Twisted Nematic) LC cells in which a chiral nematic LC with negative dielectric anisotropy was used were previously proposed by authors, and were shown to have a good colorless display image. In the conventional type of VATN cell, both substrate surfaces are treated by rubbing to obtain a slight tilt angle from the normal of each substrate. However, in the new type of VATN cell, proposed here only one side of surfaces is treated by rubbing. In this report, some E-O characteristics of new type of VATN cells are shown and investigated by experiments and simulations, and compared with that of conventional type of VATN cells. Similar T-V characteristics were obtained for both types of cell in which d/P_O=0.5. It was confirmed that LCD utilizing the optical rotatory power can be realized by the use of the new type cell as well as the conventional cell.
