摘要:
A vertical-alignment liquid crystal display device is constituted by a first substrate on which a first electrode is formed, a second substrate on which a second electrode opposed to the first electrode is formed and which is opposed to the first substrate, alignment films respectively on mutually opposing inner surfaces of the first and second substrates, and a liquid crystal layer sealed between the first and second substrates and having negative dielectric anisotropy. On the second electrode, dielectric films having a dielectric constant different from another dielectric constant of the liquid crystal layer in the layer thickness direction of the liquid crystal layer when a voltage is applied between the first and second electrodes are provided at positions respectively corresponding to the center portions of plural pixels.
