摘要： The present invention provides a multi-domain type liquid crystal display device with a vertical alignment liquid crystal layer that can get a display operation done without making the viewer sense any unnaturalness and with the decrease in optical transmittance minimized. In the liquid crystal display device of this invention, the liquid crystal layer of each pixel has liquid crystal regions in which liquid crystal molecules tilt in multiple different directions when a voltage is applied between first and second electrodes. Each pixel has an opaque portion arranged on a boundary between the liquid crystal regions. The opaque portion is provided for at least one of the substrates so that when a voltage is applied between the first and second electrodes, the liquid crystal molecules neighboring the boundary will tilt while turning one of their end portions, which is closer to the substrate with the opaque portion, away from the boundary. The opaque portion includes a first shielding layer and a second shielding layer, which overlaps with the first shielding layer with a predetermined gap left between them.
