ABSTRACT:
A liquid crystal display device that can be fabricated more simply as compared with a conventional device and suitably used in a liquid crystal display television satisfying both high pixel transmittance and wide viewing angle display characteristics is provided. The liquid crystal display device includes a pair of substrates including at least one transparent substrate, a liquid crystal layer interposed between the pair of substrates, and a liquid crystal alignment layer interposed between the liquid crystal layer and at least any one of the pair of substrates. On the liquid crystal alignment layer, a plurality of closed regions having a liquid crystal alignment direction different from the surrounding liquid crystal alignment direction are arranged. In the liquid crystal display element, each of the closed regions has such a shape that the head and tail are distinguishable along the surrounding liquid crystal alignment direction.
