Description

显示装置、反射式显示面板及其反射单元
【技术领域】
本发明涉及显示技术领域，特别涉及一种显示装置、反射式显示面板及其反射单元。
【背景技术】
如图1所示，液晶显示器面板一般由彩膜基板（CF基板）10和阵列基板（TFT基板）20对盒形成，两个基板之间的空间中封装有液晶层（LC）。
由于液晶分子自身不发光，所以显示面板需要光源以便显示图像，根据采用光源类型的不同，液晶显示器可分为透射式、反射式和透反式。
反射式液晶显示面板主要是以前置光源或者外界光源作为光源，其阵列基板采用金属或者其他具有良好反射特性材料的反射电极作为反射区，适于将前置光源或者外界光源的光线反射；反射式液晶显示面板的优点是能利用外部光源，功耗相对较低。
在现有技术的反射式液晶显示器中，为了使观看者能在各个视角都能观看到均匀的反射效果，反射层30需要设计为漫反射的反射方式，所以现有技术的反射层30设计为凹凸表面的微结构，来实现漫反射。
其具体的制作方法为：先在反射区制作一层树脂层基底，再使用光罩（Mask）进行曝光、显影、刻蚀等阵列制程在树脂层基底上形成凹凸表面的微结构，该工序需要增加一道光罩，然后在凹凸表面的微结构上，溅射金属层（银或铝）作为反射层30。
因此，现有技术制作凹凸表面微结构的反射层30工艺，需要增加额外的光罩费用，增加了制造成本；并且，在实际生产中，凹凸表面的微结构由于制造的精度限制，容易产生形态上的缺陷，影响漫反射的效果。故需要一种新的方法解决以上问题。
【发明内容】
本发明提供一种显示装置、反射式显示面板及其反射单元，以解决现有技术中需要使用光罩在树脂层基底上形成凹凸表面的微结构导致成本高、效果不好的问题。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种反射单元，其中，所述反射单元设于液晶面板外侧，外界光线经过所述液晶面板后通过所述反射单元反射并产生漫反射效果，所述反射单元包括散射层和金属层，所述散射层设于所述液晶面板外侧，所述金属层与所述散射层贴合，所述散射层用于实现所述漫反射效果，所述金属层表面为无凹凸微结构设计的平面，用于形成镜面反射。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种反射式显示面板，包括：
