We are going to do some researches about the effects onto liquid crystals (LCs) based on dynamic fingerprint chiral textures, chiral polymers, ionic materials, azobenzenes, and micro-/nano-particles. Also, we would like to develop the multi-stable LC textures and some LC electro-optic devices. Moreover, some parts of the research topics are the extended research topics of our recent studies and some nonlinear physics and optics, and they will be paid much attention in the next three years. With the funding from MOST in the past three years, my laboratory, “Liquid Crystal Electro-Optic Laboratory”, is continuously setting. I would deeply appreciate MOST for your kind support, and hope each listed topic can be completed or studied. I also hope that there will be fruitful results, including SCI papers and patents.
