Abstract:
1. A method of driving a liquid crystal display device having opposing substrates with opposing electrodes thereon and a multilayer liquid crystal layer disposed between the electrodes, the multilayer liquid crystal layer containing opposing layers of a ferroelectric liquid crystal molecules and a middle layer therebetween of a nematic liquid crystal molecules, the method comprising: applying an electric field to the opposing layers using the opposing electrodes; and in-plane driving liquid crystal molecules in the middle layer by permitting one of the opposing layers to react to the electric field, wherein the opposing layers are driven in a half V-switching mode, and their spontaneous polarization directions are different from each other so that one of the opposing layers is react to a positive electric field and the other one of the opposing layers is react to a negative electric field, and wherein the in-plane switching mode liquid crystal display is driven by a dot inversion in that the positive electric field and the negative electric field are applied to adjacent liquid crystal cells at the same time, so that the positive electric field is applied to the multilayer liquid crystal layer of a first liquid crystal cell in an odd frame and the negative electric field is applied to the multilayer liquid crystal layer of a second liquid crystal cell adjacent to the first liquid crystal cell in the odd frame.
