Abstract
We have proposed a field sequential liquid crystal display using OCB-cell with extremely fast response and have fabricated an excellent full color display without color filter as a trial. In the field sequential LCD the response (and recover) time of the bend cell is less than several milliseconds, which is extremely faster than the TN-cell or the homogeneous cell.
In this paper, the mechanism of the excellent response of the bend cell is analyzed based on the motion equations using Ericksen-Leslie's anisotropic viscosity coefficients. From the results it is clarified that the back flow slows down the response speed in almost all nematic LC cells, while the same flow effect extremely accelerates the response of the bend cell.
