This thesis demonstrates the pre-polymers in a polymer-dispersed cholesteric liquid crystals can be polymerized into a polymer film, which can eliminate the aligning capability of the homogeneous alignment layer. Thereafter, the textures of the cholesteric liquid crystals in UV-cured region can be changed from reflective planar texture to the scattered focal conic one. Additionally, the clearing temperature of the liquid crystals can be reduced by doping with chiral dopant or monomers. The cause is the increase of the impurity concentration in LCs. In other words, if the monomers are polymerized, the clearing temperature of LCs in that region should increase due to the decrease of the impurity concentration. Therefore, impurities associated with doping with monomeric and chiral dopants cause the clearing temperature of LCs in cured region to differ from that in uncured region.
本文中，我们提出在高分子聚合物薄膜之胆固醇液晶(polymer-dispersed cholesteric liquid crystals，简称PDCLCs)中，利用紫外光使PDCLC中的单体聚合成薄膜，此即为光引致聚合反应，而该薄膜将原本在表面所作的配向膜覆盖且破坏其配向能力，使胆固醇液晶由原本反射的planar结构转换成散射的focal conic结构；另外，有关液晶材料的相变温度会由於掺杂手性分子或单体而降低，此因液晶材料内『杂质』浓度增加，而造成的液晶材料之不纯度增加，最终导致相变温度降低，若搭配上述光引致聚合反应，则由於光照区之单体聚合，使该区域单体占总材料之比例下降，即不纯度降低，进而使液晶材料之相变温度上升，该区域之相变温度与未照光区有所不同。

In addition, molecular orientation behaviors induced by shearing, electric field and magnetic field were investigated. The space group of the monomers A3EO7 and A9EO7 were determined as P2〓2〓2 and P112/m by means of electron diffraction and X-ray diffraction. Liquid crystalline properties of the monomer and the polymer were studied using DSC, variable X-ray diffraction, TEM and polarized optical microscope. Both monomers exhibit monotropic liquid crystalline behavior, and they also give a metastable phase on the cooling process. The polymer PA9EO7 shows enantiotropic liquid crystalline properties. Thus the rigid polymer backbone is not a fatal defect that completely distorts the packing arrangement of the mesogenic moiety in the side chain liquid crystalline polyacetylene.

Based on the laser longitudinal mode splitting theory, a novel scheme of dual-frequency laser with large frequency-difference is presented using electrically controlled birefringence of liquid crystal, and the transmitted resonant mode splitting by birefringent of Fabry-Perot etalon has been analyzed theoretically. A new element of liquid crystal Fabry-Perot etalon is designed and fabricated, which serves as aselector and splitter of both laser longitudinal modes and Fabry-Perot etalons transmitted resonant modes. Two different experimental systems of laser-diode end-pumped Nd:YAG laser have been set up using two different LDs, and the transmission of liquid-crystal cell have been measured. When the empty LCFP is inserted in the cavity of high-power LD pumped Nd:YAG laser, the oscillation of a single laser longitudinal mode have been observed, such a result shows that the designed and fabricated LCFP element is capable of selecting single axial mode. While an anti-reflected liquid crystal cell is inserted in the cavity of Nd:YAG laser end-pumped by the high-power LD, it is difficult to confirm weather the laser longitudinal modes have been spitted or not. The subject is summarized in this thesis and the improvement of the project has been presented.

E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.
