Abstract:
1. A liquid crystal display element comprising a liquid crystal sandwiched between two substrates each having an orientation film, wherein at least one of the orientation films comprises molecules having photosensitive group and has at least two regions with different orientation anisotropies having been irradiated with polarized light of differing irradiation intensities, and wherein liquid crystal molecules have different pretilt angles such as to correspond to the orientation anisotropies of the regions of the orientation film, wherein: the liquid crystal display element is an in-plane switching-type liquid crystal display element comprising a liquid crystal layer provided between a pair of substrates and pairs of electrodes provided on one of the substrates; and the liquid crystal layer comprises, first regions provided above the electrodes, wherein liquid crystal alignment is controlled by electric field components above the electrodes; and a second region corresponding to an area between the pairs of electrodes, wherein liquid crystal alignment is controlled by transverse electric field components; wherein a pretilt angle of liquid crystal molecules in the first regions is larger than a pretilt angle of liquid crystal molecules in the second region.
