A new method of improved viewing angle of STN-LCDs was studied. Adopted method of multi-domain compensating for viewing angle of TN-LCD. In this paper, we reported the double domain STN LCD cells' structure and fabrication process, applied twice rubbing technique and lithography process and accurately orientation. We compared with the viewing angle characteristics of the conventional STN and the DDSTN. Compare with them, you will find that viewing angle of the DDSTN is more improved, it changes wide and uniform, and it is wider than viewing angle of the conventional STN. We also compared the conventional STN with the DDSTN on electric-optics characteristic each other. We analyzed the reason of contrast decrease of the DDSTN LCD, discussed the solvable method.
