Patent ID: 7999909

Claim:
A fabrication method of an in-plane switching mode liquid crystal display device, comprising: forming a pixel electrode on a first substrate; forming a common electrode on a second substrate; forming a first alignment layer on the pixel electrode; forming a second alignment layer on the common electrode; forming a first ferroelectric liquid crystal layer on the first alignment layer; forming a second ferroelectric liquid crystal layer on the second alignment layer; exposing the first ferroelectric liquid crystal layer to a first atmosphere to generate a first spontaneous polarization; exposing the second ferroelectric liquid crystal layer to a second atmosphere different from the first atmosphere to generate 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; attaching the first and second substrates with the first and second ferroelectric liquid crystal layers facing each other; and forming a twisted nematic liquid crystal layer between the first and second ferroelectric liquid crystal layers.
