Abstract

Relaxation of nematic liquid crystal (NLC) deformation near the pore in a metal-dielectric-NLC-ITO structure under the action of positive polarity of voltage is studied. Experiments indicate that deformation of NLC is observed over any size ores. Character time of relaxation depends on the size or pre and takes more than ten minutes for large (> 20 micrometers ) pores and less than a second for small (< 10 micrometers ) ones respectively. It is shown, that the electrically driven transferring of lecithin can be responsible for a long period of time relaxation.
