Abstract
A liquid crystal display device includes a ferroelectric liquid crystal layer. The ferroelectric liquid crystal molecules have pretilt directions defined by first direction vectors obtained by orthogonally projecting first imaginary vectors to each surface of a pair of substrates. The first imaginary vectors are parallel to the liquid crystal molecules in the ferroelectric liquid crystal layer in the vicinity of the substrates and directed away from each surface of the pair of substrates toward a center portion of the ferroelectric liquid crystal layer in its thickness direction. The ferroelectric liquid crystal layer has a chevron layered structure. A bending direction of the smectic layers is the same direction as the first direction vector obtained by orthogonally projecting a second imaginary vector to the substrates. The second imaginary vector is parallel to the smectic layers and is included in the same plane with the first imaginary vector and is directed away from the substrates toward the center of the ferroelectric liquid crystal layer. Walls made of insulating non-liquid crystal material are formed between the pair of substrates in a direction perpendicular to the surfa…
