ABSTRACT:
An in-plane switching mode liquid crystal display device includes a first substrate including a pixel electrode in a pixel region, a second substrate facing the first substrate and including a common electrode, a first alignment layer on the pixel electrode, a second alignment layer on the common electrode, a first ferroelectric liquid crystal layer on the first alignment layer and including a first spontaneous polarization, a second ferroelectric liquid crystal layer on the second alignment layer and including a second spontaneous polarization, a rotational direction of the first ferroelectric liquid crystal layer with respect to the first alignment layer being different from a rotational direction of the second ferroelectric liquid crystal layer with respect to the second alignment layer, and a twisted nematic liquid crystal layer between the first and second ferroelectric liquid crystal layers.
