Thin film transistor-liquid crystal display technology is that skillfully combine micro electronic technique with liquid crystal display technology. The technology of microelectronic fine processing on single crystal is transplanted to the large area glass for the processing of thin film transistor array, taking the base plate of this array and another base plate with color filter film, using the mature liquid crystal display technology to form a crystal box, then after the subsequent processes such as polarizer bonding, in the end the liquid crystal display device is formed. In the current quick developing liquid crystal display technology, since the high capacity, high definition, high quality and full color, thin film transistor-liquid crystal displays are widely favored.
