One of the important problems saving the functional properties of the liquid crystal (LC) electro-optical spatial light modulators, LC-cells and the analogs of display elements is availability of the qualitative conducting layers that withstand certain levels of applied voltages and light loadings. The mechanical hardness, laser strength, refractive and spectral parameters of the ITO-conducting coating layers structured by carbon nanotubes (CNTs) have been studied. These CNTs have been deposited using contactless laser technique under varying the electric field. Some computational and experimental alternative arguments have been performed in favor of singe-walled CNT usage and the conclusions about the benefits of the structured ITO-coatings as a conducting and orienting layer for alignment of LC-molecules have been made.
