Abstract:
1. A liquid crystal cell comprises: a first substrate that is spaced apart from a second substrate; interdigitated electrodes disposed upon said second substrate; a first alignment layer disposed on said first substrate and a second alignment layer disposed upon said second substrate and said interdigitated electrodes; liquid crystal material disposed between said first alignment layer and said second alignment layer, wherein each said first and second alignment layers are configured to align said liquid crystals in a first orientation when a voltage is applied to said electrodes; and polymer fibrils disposed in said liquid crystal material and positioned proximate to each said first and second alignment layer, wherein said polymer fibrils align said liquid crystals in a second orientation when no voltage is applied to said electrodes; wherein said polymer fibrils are formed from a polymer having a concentration of between about 0.2% to 3%.
