Abstract:
1. A fabrication method of an in-plane switching mode liquid crystal display device, comprising: supplying a pixel electrode on a first substrate; supplying a common electrode on a second substrate; disposing a first alignment layer on the pixel electrode; disposing a second alignment layer on the common electrode; forming a first ferroelectric liquid crystal layer by coating a first ferroelectric liquid crystal of an isotropic phase on the first alignment layer; forming a second ferroelectric liquid crystal layer by coating a second ferroelectric liquid crystal of an isotropic phase 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 to generate a second spontaneous polarization wherein the second atmosphere is different from the first atmosphere; attaching the first and second substrates such that the first and second ferroelectric liquid crystal layers face each other; and interposing a twisted nematic liquid crystal layer between the first and second ferroelectric liquid crystal layers, wherein a rotational velocity of the first spontaneous polarization is different from a rotational velocity of the second spontaneous polarization.
