Abstract:
1. A liquid crystal display unit comprising: a first substrate and a second substrate opposing each other; a first electrode pattern formed on said first substrate; a second electrode pattern formed on said second substrate; a vertical alignment film formed on at least one of said first and second substrates and covering at least one of said first and second electrode patterns; a liquid crystal layer sandwiched between said first and second substrates; and a pair of polarizer plates disposed outside said first and second substrates and having crossed-Nicols; wherein: an edge of at least one of said first and second electrode patterns includes a sawtooth pattern comprising a plurality of serially connected teeth with edges of the teeth being parallel and perpendicular to one of said crossed-Nicols; one of said first and second electrode patterns includes a segment electrode; the other of said first and second electrode patterns includes a common electrode; an overlapping area of said segment electrode and said common electrode defines a pixel; and said pixel is defined by a first pair of parallel sides and a second pair of parallel sides, and each of said first and second parallel sides is parallel or perpendicular to one of said crossed-Nicols.
