Abstract

In this paper we investigated the transcription of liquid crystal (LC) alignment method by using memory effect of nematic(N) LCon polymide(PI) surface with side chain as for non-rubbing alignment techniques. That the monodomain alignment of aligned NLC is observed by microscope textures in the cells on PI surface with side chain. We obtained that the pretilt angle of NLC are generated about 3.7$^{\circ}$on PI surface. We suggest that the LC alignment by using transcription alingnment method is attributed to memory effect of NLC on PI surface.
