The optically compensated bend (OCB) nematic liquid crystal display (LCD) that used a configuration molecular orientation called pi-cell has attracted much attention due to its superior characteristics such as a fast response time and a wide viewing angle. The OCB-type LCD has one serious drawback in which it needs the initial transition operation from the splay alignment to the bend alignment by applying high voltage at start-up, and always needs an operating voltage higher than its critical voltage to maintain the bend alignment. To mitigate this problem, polymer stabilized method has been proposed. In this research, the transient response characteristics of the polymer stabilized pi cell are investigated. The transient response speed of the pi cell being in the bend alignment decreased by polymer stabilization. The transient response speed depended on the rotational viscosity.
