Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a reflective liquid crystal display device. 【Background technique】 [0002] Liquid crystal display devices are generally divided into three types: reflective liquid crystal display devices, transmissive liquid crystal display devices and semi-transmissive liquid crystal display devices according to the different light sources used. The reflective liquid crystal display device uses an external light source to provide the light beam required for display. The light source is mainly natural light, and it can also be an external artificial light source. It is generally installed outside the reflective liquid crystal display device. This type of liquid crystal display device can save power consumption. Reflective liquid crystal display devices have been widely used in videophones, portable digital assistants (Personal Digital Assistant, PDA) and various computer devices. [0003] s...
