We have developed a dual‐domain vertically aligned TFT‐LCD by irradiation with unpolarized UV light from tube‐type light source. We reduced disclination by fabricating protrusions and by optimizing the alignment material. The transmittance of a 15‐inch diagonal TFT‐LCD is twice that of IPS LCD, 1.5 times that of conventional MVA‐LCD and 1.1 times that of TN‐LCDs with Wide‐View film.
