Color Paste for Color Resist
TFT-LCD is a variant of liquid crystal display that uses thin film transistor technology to improve image quality and is mainly composed of Back Light, Polarizers, TFT Substrate, Liquid Crystal, and Color Filter etc. Color Resist is one of the leading factors for Color Filter; likewise, Color Paste plays an important role in Color Resist - deriving from Color Paste by adding some binder, monomer, additives and so on.

LCD Color Paste – BM & R、G、B
BM: Color filter needs some black stripes to increase the contrast, avoid the electric leakage and cover up some oblique light while display, the so-called Black Matrix.

R, G, B: When the Color Filter is pervious to the light from the Back Light, the colors of red, green and blue would occur; that is why the LCD is colorful. The three primary colors constitute all the other colors.
