Abstract
A liquid crystal display device in which alignment control in a vertical-alignment-type liquid crystal layer is excellent at a side portion or a corner portion of a pixel electrode. The liquid crystal display device includes a pixel electrode including openings of slits as an alignment control mechanism, a common electrode including linear protrusions as an alignment control mechanism, the electrodes opposed to each other, and a vertical-alignment-type liquid crystal layer sandwiched between the electrodes, wherein the linear protrusion is placed at a position where the linear protrusion controls alignment in the liquid crystal layer inside a position where an oblique electric field generated at the edge of an corner portion of the pixel electrode at the time when a voltage is applied between the electrodes controls the alignment in the liquid crystal layer.
