Polymer networks are employed in vertical-aligned liquid crystal (LC) cells to stabilize the LC molecular configuration under the in-plane field driving. Two different polymer morphologies, respectively produced by the monofunctional and bifunctional acrylate monomers, are assembled on the glass-substrate surface. The enhanced electro-optical performance is observed on the LC cell with bifunctional acrylate polymer networks, and the appropriate display cell is developed at an optimum concentration of 2wt%. This type of polymer-LC cell shows the fast turn-off and turn-on responses at the low driving voltage, which are attributed to the strong anchoring and the stable LC reorientations, respectively. Furthermore, around 30% improvement in the gray-level response on the 2-wt%-TA-9164-polymer-LC cell is successfully achieved, as compared to the pure LC cells.
