In this case, the first region may be an optically aligned region, or the second region may be an optically aligned region. When optical alignment is to be carried out, the region to be given optical alignment is, for example, selectively irradiated with ultraviolet rays. COPYRIGHT: (C)2007,JPO&INPIT
