Status and Development Trends of Upstream Materials for Liquid Crystal Display Industry in China

液晶显示产业上游材料中涉及的化学品范围很宽．种类繁多，受篇幅限制不可能在一一例举。这里仅就重要的几种材料作一介绍。

The upstream materials for industry of liquid crystal display are mainly six kinds as follows, liquid crystal materials, color filter film, photoresist, polarizer, touch screen and backlight module. Liquid crystal material is the upstream material with top technology and best industrial base in China. The main raw materials for color filter film produced by pigment dispersion method are color photoresist, indium tin oxide based target materials and black matrix materials. There is no production capacity of photoresist yet for TFT-LCD in China mainland. The polarizer was manufactured by dyeing with dichroic organic dyestuff, and the technology for producing polarizer was depended mostly (80%) on the technique of the Japanese enterprises.
