Abstract

The Patterned vertical alignment (PVA) mode has many advantages such as perfect dark state at the normal direction and wide viewing angle. However, PVA mode needs additional process to pattern electrodes of both substrates and complicated assembly process. Moreover, this mode shows slow response time. To overcome these problems, we use plane shape ITO on top substrate instead of patterned electrode and form proper tilt angle of LC director on the surface while maintaining these original merits. Consequently, we achieve fast response time and improve transmittance.
