    摘要: The present invention relates to a liquid crystal display in multiple alignment or MVA mode in which liquid crystal molecules having negative dielectric anisotropy are aligned differently, and it is an object of the invention to provide a liquid crystal display having improved response characteristics while suppressing any reduction in transmittance. In a liquid crystal display having an electrode formed on each of opposite surfaces of two substrates facing each other with a predetermined gap therebetween, vertical alignment films 2 and 4 formed on the electrodes and liquid crystal molecules 6 having negative dielectric anisotropy sealed between the two substrates, there is provided singular point control portions 10a through 10d and 8 for controlling singular points (+1 or −1) of an alignment vector field of the liquid crystal molecules 6 such that they are formed in predetermined positions when a voltage is applied between the electrodes and for thereby controlling the alignment of the liquid crystal molecules 6 based on the singular point thus formed.
