Abstract:
The invention relates to a method of manufacturing a liquid crystal display device wherein a liquid crystal mixture having positive dielectric anisotropy or negative dielectric anisotropy is interposed between a first substrate and a second substrate, the liquid crystal mixture comprising liquid crystal molecules, a self assembling photoalignment agent, a polymerisable compound, and wherein said LC mixture is photoaligned by irradiation with linearly polarised ultraviolet light and then cured by irradiation with ultraviolet light.

Claim (Index 1):
