1. A method of fabricating a liquid crystal display device, comprising:

  • forming a common electrode and a color filter layer on a first substrate;

    constructing a second substrate from an array substrate on which are formed a gate bus line layer, a gate insulating film layer, a drain bus line layer, a protective film layer, and a pixel electrode layer;

    forming fine slits in the pixel electrode layer in such a direction that a pixel is divided by the slits into at least two sub-regions;

    forming on each of the two substrates a vertical alignment film for vertically aligning liquid crystal molecules;

    forming a liquid crystal layer by filling an n-type liquid crystal composition having a negative dielectric anisotropy into a gap between the two substrates, the liquid crystal composition containing an ultraviolet curable resin having a liquid crystal backbone;

    radiating ultraviolet light while applying to the liquid crystal molecules a voltage not smaller than a threshold value of the liquid crystal molecules, thereby defining the direction in which the liquid crystal molecules tilt in the presence of an applied voltage; and

    arranging two polarizers on top and bottom surfaces of the liquid crystal display device in a crossed Nicol configuration with the absorption axes thereof oriented at an angle of 45 degrees to the alignment directions of the liquid crystal molecules.
