Effect of the polarisation direction and incident angle of a UV light on the electrooptical response of the polymer-stabilised vertically aligned in-plane switching liquid crystal

We investigated the effect of the polarisation direction and incident angle of a UV light on the electrooptical properties of the polymer-stabilised vertically aligned in-plane switching (PS-VAIPS) liquid crystal. The PS-VAIPS sample cured with a UV light whose polarisation was parallel to the projected direction of the in-plane electric field showed greater transmittance, faster rising time and slower falling time than the sample cured with a UV light with a perpendicular polarisation to the electric field. In addition, the PS-VAIPS sample showed slower rising time and faster falling time with increasing incident angle of the UV light.
