Dynamic characteristics of vertically aligned liquid crystal device using a polymer wall associated with the boundary condition of alignment layer

Voltage-dependent liquid crystal (LC) reorientation was analyzed in a vertically aligned nematic liquid crystal display with a polymer wall (called a locked-super homeotropic (LSH) device) through the LC textures. The LC textures generated have a singularity of S=+1, however, they were strongly dependent on the order of fabrication between the polymer wall and the vertical alignment layer, generating either pure radial or twisted radial orientation of the mid-director. In this article, we investigate how the boundary condition of the alignment layer on a wall surface affects the dynamics of LCs in the LSH mode.
