Abstract
We have studied voltage-dependent LC dynamics of the locked super homeotropic (LSH) mode, where the vertically aligned LCs are locked by surrounding walls such as cubic, hexagon and cylinder. Time-resolution study of the LC texture shows that the LC director is not stable enough during an instantaneous LC reorientation when a voltage is applied. To improve dynamic characteristics, we propose a new cell structure where the bend and twist deformation is controlled by polymer wall plus an oblique electric field through patterned electrode. Consequently, dynamic characteristics of vertically aligned LC mode surrounded by polymer walls are greatly improved.
