The relations between the polymer morphology and electro-optic properties in polymer stabilized cholesteric textures (PSCT) were investigated. SEM analysis revealed that the polymer matrix consisted of submicron-order-diameter spherical particles, which are connected with each other and forms three-dimensionally networked wire. The network spacing which evaluated from a number of the polymer particle in volume was the main factor determining the electro-optic characters of the device. With the larger network spacing, the improved properties of PSCT device such as lower driving voltage and higher contrast ratio were attained.
