ResumoThe threshold behavior of the in-plane switching (IPS) mode liquid-crystal cells with different (asymmetric) anchoring strength at two liquid-crystal/substrate interfaces was investigated by linear stability analysis. Similarity in stability characteristics between the IPS mode and the surface stabilized ferroelectric mode was clarified. The analysis showed that, with parallel rubbing of the two substrate surfaces, only the (symmetric) switching initialized from the center of the liquid-crystal layer will occur even with the asymmetric surface condition. This means that the basic switching process of the IPS mode does not change with the asymmetricities of the surface conditions.
