A theoretical expressions are devived for a range of the d/P 0 ratio in which two distinct states exist in the equilibrium condition and the lower limit of azimuthal anchoring energy exhibiting two distinct states. Theoretical calculations have been made on the bi‐stable energy curve which has two minimal energy levels corresponding to bi‐stable states. It has been shown that the energy barrier between the two states mainly originates from the azimuthal anchoring energy and the height of the energy barrier is affected by the d/P 0 ratio and cell thickness.
