초록
We report viewing angle characteristics of the Ultra-FFS TFT-LCD. The FFS mode is known to exhibit both a wide viewing angle and high transmittance, owing to the approximated in-plane rotation of the LC director. Nevertheless, in the bright state, the device shows bluish and yellowish color parallel and perpendicular to the LC director at off-normal directions since the LC director rotates onl.v in one direction, and in addition, the grey scale inversion exists in large oblique viewing angle. However, the Ultra-FFS shows no grey scale inversion and no color shift in wide viewing angle range.
