Effect of Polymer Network Made of Liquid Crystalline Diacrylate on Characteristics of Liquid Crystal Display Device

Abstract
We investigated the effect of the polymer network, which is made of a liquid crystalline diacrylate in a nematic liquid crystalline host, on the alignment and motion of liquid crystals. We found that the polymer network has strong influence on the alignment and motion of the liquid crystals even with the low concentration of 2 wt% of the liquid crystalline diacrylate. The polymer network prepared in an electric field gives a uniform alignment of liquid crystals with a tilt angle to the alignment layer because of good orientation of the polymer network. Furthermore, we report the effect of the oriented polymer network on the characteristics of a twisted nematic (TN) device.
