High-contrast SSFLC display utilizing naphthalene-base liquid crystal materials and conductive orientation films (Invited Paper)

摘要

Abstract: This paper reports the electrical properties of a surface stabilized ferroelectric liquid crystal display provided by an almost ideal bookshelf layer structure. The bookshelf layer structure is obtained by ordinary rubbed polymer film cell by utilizing a particular liquid crystal material; naphthalene-ring contained liquid crystals. First, we show the layer structure of the naphthalene base FLCs analyzed by x-ray diffractions. Second, the electro-optic switchings of the naphthalene base FLCs are discussed. Then the effect of the depolarization field on the polarization switching is mentioned. Some polarization switching phenomena in conjunction with the the conductivity of the orientation layer is shown. Finally, we mention our multiplexed FLC prototype. It has 640 $MUL 201 pixels, shows 40:1 contrast ratio, and 40% transmittance. !19
