Abstract
A ferroelectric liquid crystal display device is described. The device has a pair of substrates having at least an electrode film and an alignment film, and a complex made of a ferroelectric liquid crystal material and a polymer material disposed between the substrates. The complex has a network structure such that the network structure stabilizes the orientation of molecules of the ferroelectric liquid crystal material. Directions of pretilt angles of the molecules of the ferroelectric liquid crystal material located at interfaces between the substrates and the ferroelectric liquid crystal material are substantially identical. The ferroelectric liquid crystal material has a chevron layer structure, and a bending direction of the chevron layer structure is substantially identical to the directions of the pretilt angles of the molecules at the interfaces.
