Abstract
A liquid crystal display device including a pair of substrates, an electrode and an alignment layer formed on each of the substrates, and a liquid crystal filled between the pair of substrates. The alignment layer of one of the pair of substrates is treated so that the alignment layer is divided into a plurality of stripe regions including a first stripe region and a second stripe region adjacent to the first stripe region, the first and second stripe regions extending parallel to each other and forming a first boundary therebetween. A direction of alignment of liquid crystal molecules on the first stripe region is opposite to a direction of alignment of liquid crystal molecules on the second stripe region, and directions of alignment of liquid crystal molecules on the first and second stripe regions are parallel to the first boundary. A shading layer is provided to cover the first boundary.
