Abstract:
The liquid crystal display device includes a first substrate, a second substrate opposed to the first substrate, and a vertically aligned liquid crystal layer interposed between the first and second substrates, and has a plurality of pixels arranged in a matrix having rows and columns. Each pixel includes a first electrode formed on the first substrate, a second electrode formed on the second substrate, and the liquid crystal layer interposed between the first and second electrodes. The first substrate has a shading region in gaps between the plurality of pixels, and a wall structure is placed regularly on the surface of the first substrate facing the liquid crystal layer in the shading region. The first and second electrodes have at least one opening formed at a predetermined position in the pixel. At least an arbitrary row or column of pixels is composed of first pixels each having the first electrode to which a voltage of positive polarity with respect to the potential at the second electrode as the reference potential is supplied and second pixels each having the first electrode to which a voltage of negative polarity is supplied, arranged alternately, in a given vertical scanning period. At least one liquid crystal domain having axisymmetric alignment is formed when at least a predetermined voltage is applied across the liquid crystal layer, and the center axis of the axisymmetric alingment of the at least one liquid crystal domain is formed in or near the at least one opening.
