摘要： In a liquid crystal display device including (1) a pair of substrates on the surface of which a transparent electrode and an alignment film are formed in turn, and the alignment films are arranged with a gap so that the films face each other, (2) a liquid crystal which fills the gap, (3) two polarizer plates holding the pair of substrates between them, and (4) a driving circuit connected to the transparent electrodes for applying a voltage between both substrates, the improved display device including a vertically arranged splayed nematic liquid crystal wherein a nematic liquid crystal which is substantially free from a chiral liquid crystalline compound and has a negative dielectric anisotropy is used as the liquid crystal; molecules of the liquid crystal between the pair of the substrates are oriented so that their molecular axis are arranged on planes orthogonal to the substrates; liquid crystal molecules, in the vicinity of the surface of the substrates, are oriented vertically or semi-vertically so that the angle between the axis of the molecules and the substrates is in the range of 90 to 45.degree.; and liquid crystal molecules, in other portions, are oriented so that the angle between the axis of the molecules and the substrates becomes gradually smaller as the position of the molecules approaches the center portion of the gap between the substrates, and the axis becomes substantially parallel to the substrates in the center portion of the gap between the substrates.
