The antiferroelectric liquid crystals exbibit various subphases and various models have been proposed. Although the molecular arrangements of SmC and SmCA are clearly established, these subphases have not been clarified yet. In the SmC γ and AF to which Ising model or clock model gives expression, we simulated the selective reflection and the optical rotatory power (ORP) by 4×4 matrix method. Simulation results show that SmC γ and AF in the clock model can't arise selective reflection and ORP. We proposed possibility of a new modified structure of AF, remarking the ORP in the vicinity of transition point and conoscope images. The modified 4-layer superlattice structure of AF based on the lising model can successfully explain the optical character.
