Abstract

Base on FLC free energy, the asymmetrical alignment techniques were proposed to suppress the alignment defects of half- V mode ferroelectric liquid crystal (HV-FLC) devices. Alignment layers with opposite surface polarities and different anchoring energies were applied to controlled the sign and value of polar surface coefficient (γ2). respectively. The asymmetrical cells of PIrub-PIplasma (rubbed polyimide (PI) and plasma treated PI surfaces), PVArub-PIplasma (rubbed polyvinyl alcohol (PVA) and plasma treated Pl surfaces), and PVArub-PI rub (both rubbed PI and PVA) alignment conditions present mono-domain alignment textures under slow cooling process. Among these alignment pairs, the PVArub-PIrub treated cell, with larger difference in γ2 values, appeared to have better alignment. A 2.4" prototype TFT-LCD was presented by PVArub-PIrub treated surfaces.
