Abstract
A liquid crystal display device including a pair of spaced and opposed substrates, an electrode and a first alignment layer formed on one substrate, an electrode and a second alignment layer formed on the other substrate, and liquid crystal filled between the pair of substrates. The first alignment layer defines two regions of different alignment directions, within one pixel, with the two regions of the first alignment layer being separated by a first boundary, where the two different alignment directions of the first alignment layer are generally parallel to the first boundary, but extend in opposite directions, and where each region of the first alignment layer is treated to realize an alignment with a pretilt angle by the irradiation of ultraviolet rays. The second alignment layer defines two regions of different alignment directions, within the one pixel, with the two regions of the second alignment layer being separated by a second boundary, where the two different alignment directions of the second alignment layer are generally parallel to the second boundary, but extend in opposite directions, and where each region of the second alignment layer is treated to realize an alignment with a pretilt angle by the irradiation of ultraviolet rays. The first boundary crosses said second boundary.
