Patent ID: 7405795

Claim:
An in-plane-switching mode liquid crystal display device, comprising: a first ferroelectric liquid crystal layer including first ferroelectric liquid crystal molecules on a first substrate; a second ferroelectric liquid crystal layer including second ferroelectric liquid crystal molecules on a second substrate, the first and second substrates being bonded to each other with a space therebetween; and a nematic liquid crystal layer including nematic liquid crystal molecules at the space between the first and second ferroelectric liquid crystal layers, the first and second ferroelectric liquid crystal layers including a photo-polymerizational monomer, wherein the nematic liquid crystal layer is substantially driven in plane by the first and second ferroelectric liquid crystal layers, wherein the molecules of the first and second ferroelectric liquid crystal layers rotate along a virtual cone, are driven in plane, and induce the in-plane-drive of the nematic liquid crystal molecules.
