Abstract

We studied a periodic boundary effect in liquid crystal (LC) devices with multi-domains consisting of homeotropic and hybrid alignments. In this configuration, the surface anchoring energy was determined using the LC director-distorted length near the domain boundary, in a linear approximation of the director profile based on the continuum theory. The distorted length was measured in the LC binary diffraction grating.
