-24-Training Manual Principle of LCDImprovement Technology of LCD Display6-4 MVA (Multi-domain Vertical Alignment) SystemIn the MVA system, the (alignment) film is arranged so that the liquid crystal molecules are stood vertical-ly. The MVA system combines vertical alignment with the Multi-domain system. By vertically aligning theliquid crystal molecules, the influence of optical interception is lost, and the angle of view and contrastare improved.A type of material is used that causes the liquid crystal molecules to become vertical to the glass platewithout supplying voltage. (Nega-Nematic liquid crystal*)In the MVA system, attaching the boss by resin and making the liquid crystal molecules stand diagonallyon the transparent electrode make multiple alignment domains. Therefore, since the rubbing process canbe skipped at the alignment film production, manufacturing becomes easier compared with the multi-domain system.✐ Generally, a Posi-Nematic system is used that aligns the liquid crystal molecules by supplying voltage.PolarizedBoardPolarizedBoardGlassPlateAlignment Film(Right)Liquid Crystal Molecule(Nega-Nematic)GlassPlateTransparent Electrode(Pixel, TFT)Alignment Film(Left)Transparent Electrode(Common)BossFig. 24 MVA (Multi-domain Vertical Alignment) System
