Abstract
The performance of liquid crystal (LC) cells with asymmetric slit-patterned electrode structures in various applied field configurations is studied in detail, by measuring the interference fringe patterns and simulating the two-dimensional director distributions of liquid crystal by a finite element method (FEM). We investigate the molecular orientation effects in inhomogeneous electric fields and the optical properties of these cells as cylindrical microlenses, and show that disclinations, which deteriorate the lens properties, can be eliminated by adopting an appropriate applied field configuration.
