Abstract
One of the most notorious problems with ferroelectric liquid crystal is obtaining zigzag free bistable devices. By investigating the balance between surface azimuthal anchoring energy and bulk elastic energy within the confined chevron layer geometry of C1 and C2, we propose that it is possible to get a zigzag free C1 state by low azimuthal anchoring alignment at a low pretilt angle. The critical azimuthal anchoring coefficient for the defect free C1 state is calculated. Its relationships with elastic constant, chevron angle, as well as surface topography effect are also discussed.
