How to obtain defect‐free ferroelectric liquid crystal displays(FLCDs) is the most important problem in developing liquid crystal displays(LCDs). In this report, a phenomenological theory of transition between C‐1 state and C‐2 state in FLC cell has been firstly suggested. Theory the free energy that includes bulk elastic and surface parts has been simulated depending on the parameters such as surface topography, anchoring energies, thickness of LC medium and so forth. The critical conditions of the state transition from C‐1 to C‐2 have been determined. Based on this theory, we succeeded in fabricating defect‐free FLCDs with uniform C‐2 state by rubbing and that with uniform C‐1 by photoalignment technique.
