(c) irradiating the photoreactive layer with polarized pulsed UV light from a UV lamp, thereby forming an optical alignment layer,
wherein a flash voltage of the polarized pulsed UV light is from 1 kV to 4 kV,
wherein the time period for said irradiating the photoreactive layer with the polarized pulsed UV light is from 0.1 seconds to 10.0 seconds, and
wherein a distance between a source of the polarized pulsed UV light and the photoreactive layer is from 0.5 cm to 10.0 cm.
