Homeotropic alignment of liquid crystals on ITO surface using LBL assembly

摘要

In this work, the very thin layer-by-layer (LBL) film that was constructed by dip coating method on indium tin oxide surface can be used in liquid crystal (LC) displays devices. The obtained results indicate that the ultrathin LBL film shows the homeotropic alignment layer, and a uniform vertical alignment of LC molecules was gained very easily. The progress of vertical-aligned LC cells with a LBL layer was evaluated. The obtained threshold voltage and response time of the LC cell were 2.472V and 12.5ms, respectively. So, the competitive performance of the LC cell could allow new sign at a low-cost budget with rubbing process in LC display technology.
