The relationship between the polar (out-of-plane tilt) anchoring strength and the memory capability of surface-stabilized ferroelectric liquid crystal displays (SSFLCD) with rubbed polyimide (PI) surfaces as alignment layers has been investigated. The polar anchoring strength of nematic liquid crystals (NLC) on rubbed PI surfaces with low polymer concentration is weak compared to that on PI surfaces with high polymer concentration. However, we have found that the memory capability of SSFLC on rubbed PI surfaces with low polymer concentration is high compared to that on rubbed PI surfaces with high polymer concentration. It is expected that the weak anchoring strength is attributed to the good memory capability of the SSFLCD on rubbed PI surfaces.
