1.什么是液晶液晶是一种几乎完全透明的物质。在物理学上把物质分为三态,即固态、液态和气态。其实所谓的三态只是大致的区分,有些固体物体可以再被细分出多种状态。同样,液体也可具有不同的状态,其中分子排列具有方向性的液体就称之为液态晶体,简称液晶。2.液晶有哪些种类液晶种类很多,主要有近晶型、胆甾型和向列型。目前用在显示技术上最重要的原材料就是向列型液晶。3.液晶分子有哪几种 1. What is liquid crystal LCD is an almost completely transparent material. Physics is divided into three states of matter, that is, solid, liquid and gaseous. In fact, the so-called tri-state is only roughly the distinction between some solid objects can be subdivided into a variety of states. Similarly, the liquid can also have different states, in which the molecular arrangement of liquid with directivity is called liquid crystal, referred to as liquid crystal. 2. What kind of LCD There are many types of liquid crystal, there are mainly smectic, cholesteric and nematic. Currently used in display technology is the most important raw material for nematic liquid crystal. 3. What kind of liquid crystal molecules
