A simple model for thresholdless antiferroelectric liquid crystal displays is presented, in which the typical thresholdless characteristic is caused by a negative interaction coefficient between the alignment layer and the liquid crystal. This negative interaction coefficient may be caused by the pairing of transverse dipole moments in adjacent layers. It causes a maximum tilt of the liquid crystal molecules in the zero‐field antiferroelectric equilibrium state, which then evolves gradually to the ferroelectric state with increasing electric field.
