一、液晶概念及其发展简史从宏观性质上说,液晶是一类既具有液体那样的流动性,又具有晶体那样的结构有序性,以致在光学、电学、磁学和力学上都具有各向异性的一类有机物。但并不能因此就把液晶称为液态晶体,而应该将其看作一种高度各向异性的流体1888年,奥地利植物学家莱尼茨尔(FReinityer)在合成胆固醇酯时,发现此类化合物在由固态(分子排列长程有序)转为液态(分子排列杂乱无章(的过程中,存在着一种混浊 First, the concept of liquid crystal and a brief history of development Macroscopically speaking, liquid crystal is a kind of liquid that has both fluidity, but also with the crystal structure that order, so that the optical, electrical, magnetic and mechanical have Anisotropy of a class of organic matter. But liquid crystals can not therefore be called liquid crystals, but rather as highly anisotropic fluids. In 1888, the Austrian botanist FReinityer found that such compounds In the solid (molecular arrangement of long-range orderly) into a liquid (the molecular arrangement disorderly process, there is a turbidity
