Abstract

We investigated the high pretilt angle effects on electro-optical properties of ion beam (IB)-irradiated liquid crystal cells on a blended polyimide surface. High pretilt angle of liquid crystals IB-irradiated on a blended polyimide surface including such as 5% and 10% of homeotropic polymer contents can be achieved. The threshold voltages of IB-irradiated twisted nematic (TN) cells on a blended polyimide surface decrease with increasing the pretilt angle. Also, the rising time of IB-irradiated TN cells decreases with increasing the pretilt angle. However the decay time of IB-irradiated TN cells increases with increasing the pretilt angle. Consequently, the electro-optical properties of IB-irradiated TN cells depend strongly on the pretilt angle in a blended polyimide surface.
