CRT（Cathode Ray Tube的简称）阴极射线管显示器的工作原理是通电后灯丝发热，阴极被激发，发射出电子流，电子流受到带有高电压的内部金属层的加速，经过透镜聚焦形成极细的电子束，打击在荧光屏上，荧光粉受到高速撞击之后发光。
LCD （ Liquid Crystal Display 的简称）液晶显示器。目前主流的LCD是TFT-LCD（薄膜晶体管液晶显示器），是由原有的液晶显示技术发展扩展而来的。 与CRT的原理完全不同的是，LCD 的构造是在两片平行的玻璃基板当中放置液晶盒，下基板玻璃上设置TFT（薄膜晶体管），上基板玻璃上设置CF（彩色滤光片）。TFT液晶为每个像素都设有一个半导体开关，以此做到完全的单独的控制一个像素点，液晶材料被夹在TFT玻璃层和颜色过滤层之间，通过改变刺激液晶的电压值进而控制液晶分子的转动方向，从而控制每个像素点偏振光出射与否而达到显示目的，控制最后出现的光线强度与色彩。
 技术问题
伴随着液晶显示技术的飞跃发展，LCD的性能也在不断提高。因此LCD被广泛应用在各个领域，并且LCD在各个领域发展迅猛，但是随之而来也会遇到一些挑战。其中比较显著的问题是，当前的LCD在很多情况下不能够满足某些特定场合的实用需求。在此情况下，需要将LCD从直板式向柔性方向发展。但是，由于目前的LCD显示器非自发光模式，需要某种形式的外界光源，而目前的LCD背光源为刚性，无法弯折，造成柔性 LCD无法实现。
 技术解决方案
本发明的目的是：提供一种柔性LCD及其制备方法，以解决目前背光源为刚性进而导致LCD无法弯折的现状，满足某些特定场合的实用需求，扩大LCD的应用领域，进一步地推动LCD的发展。

如图1所示，一种柔性LCD，包括第一柔性衬底1；阳电极2，电致发光层3，阴电极4。第一衬底1可以是塑料衬底、不锈钢衬底、超薄玻璃衬底、纸片衬底以及生物复合薄膜衬底中的一种。第一衬底1主要由透光性能良好的聚酯类薄膜组成，如PET，PI（Polyimide的简称）聚酰亚胺、金属箔片、超薄玻璃等。阳电极2设于第一柔性衬底1的上表面。电致发光层3设置于阳电极2的上表面。阴电极4设置于电致发光层3的上表面。
如图1所示，一种柔性LCD，还包括透明保护层5，透明保护层5覆盖于阴电极4的上表面。透明保护层5包括SiNx，SiOx等，主要目的是为了防止电致发光层3的电致发光涂层材料被水气侵蚀和氧化。

第一聚酰亚胺配向膜层7以及第二聚酰亚胺配向膜层9由一种用来制作LCD配向膜的化学液，分别涂布于TFT和CF侧，然后进行摩擦( Rubbing )制程，配向膜表面会因配向滚轴上摩擦布的毛羽摩擦而被刷出一定方向排列的沟槽，印刷在导电玻璃上经过烘烤后成为配向膜，配向膜上的液晶材料会因分子间作用力而达到走向效果，并给液晶分子提供一个预倾角，使得液晶分子的旋转方向一致性更好。预倾角会影响驱动电压，预倾角越大，所需加的驱动电压越小。
第一氧化铟锡膜层6以及第二氧化铟锡膜层10可以由氧化铟锡(透明导电薄膜)在钠钙基或硅硼基基片玻璃的基础上，利用溅射、蒸发等多种方法镀上一层氧化铟锡膜加工制作成的，因此氧化铟锡膜具有良好的导电性和透明性以及柔韧性。
电致发光层3的电致发光涂层材料可以是有机物，也可以是无机物，优选采用全色显示材料，进而实现柔性LCD的全色显示，提高发光效率。
电致发光层3的电致发光涂层材料可以采用蒸镀、打印、均相沉积法或者气相合成法中的一种方法发制备实现，电致发光涂层材料提取方法多，进而降低柔性LCD的制备成本。
电致发光层3的电致发光涂层材料厚度优选为微米级，由此制成的柔性LCD能够达到更薄、轻质、便于携带的效果。
阳电极2具体可以采用由氧化铟锡（氧化铟锡膜）、氧化铟锌（IZO）等透明导电膜构成的透明电极，具有透光性，阳电极2作为用于向电致发光层3注入空穴的阳极发挥作用。所述阳电极由可柔性弯折材料组成，例如：（ Pedot）聚二氧乙基噻吩、氧化铟锡膜等其他可柔性弯折材料。
阴电极4可以采用由氧化铟锡、氧化铟锌（IZO）等透明导电膜构成的透明电极，具有透光性；阴电极4也可以采用例如由膜厚1mm的镁银合金（MgAg）和膜厚19mm的银（Ag）的蒸镀膜构成的半透明电极，具有半透射性。阴电极4作为用于向电致发光层3注入电子的阴极发挥作用。阴电极4由可柔性弯折材料组成，例如：（Pedot）聚二氧乙基噻吩、氧化铟锡膜等其他可柔性弯折材料。
