Paper Abstract

We investigated polymer networks made of a liquid crystalline monomer and found that they have strong influence on alignment of liquid crystal host even with the low concentration of 2%. A nematic crystal with 2% monomer dopant was cured under UV light with a controlled electric field presented. Increase of pretilt angle of liquid crystal was observed. We doped a low percentage monomer in 270 degree(s) twisted SBE device and polymerized to form a polymer network with a electric field presented. Compare with those SBE devices without polymer dopant, the polymer network stabilized SBE device performance lower driving voltage and the stripes formation was significantly eliminated because higher pretilt angles were formed. The effect of the amount of polymer and polymerizing electric field was also investigated.
