We have studied the fringe field switching (FFS) mode with the positive dielectric anisotropy for the fast response time. The factors such as the physical properties of the LC, the cell gap, and the rubbing angle were critical for the fast response time of the FFS mode. The response time became 10 ms faster when the rotational viscosity of the new LC is 20 mPa.s lower than the conventional LC. When the cell gap changed from 3.6 ${mu}{ extrm}{m}$ to 3.0 ${mu}{ extrm}{m}$, it was possible to achieve the total response time and response times associated with grey-to-grey transitions under 16 ms. And the response times including grey-to-grey transitions become fast as the rubbing angle decreases.
