ABSTRACT:
An in-plane switching mode liquid crystal display device includes a first substrate, a second substrate, ferroelectric liquid crystal layers between the first and second substrates disposed substantially at respective surfaces of the first and second substrates, the ferroelectric liquid crystal layers arranged by an exposure to one of an amphiphobic medium and an amphiphilic medium, a nematic liquid crystal layer between the ferroelectric liquid crystal layer of the first substrate and the ferroelectric liquid crystal layer of the second substrate, and electrodes disposed on surfaces of each of the first and second substrates to vertically apply an electric field to the ferroelectric liquid crystal layers and to the nematic liquid crystal layer.
