Abstract:
A liquid crystal display panel and a liquid crystal display device in which a position of a singular point of pinwheel alignment is controlled, thereby suppressing rough-grained image and generation of image retention, and in which the response time is improved. A pair of substrates each include an electrode, at least one of the pair of substrates includes a vertical alignment film and a photopolymerized polymer, the electrode on one of the pair of substrates has such a shape as to provide pinwheel alignment of the liquid crystal molecules upon application of a voltage and is partly provided with openings for surrounding a singular point of the pinwheel alignment and keeping the singular point within the electrode.
