Patent ID: 8194220

Claim:
An in-plane switching mode liquid crystal display device, comprising: a first substrate; a second substrate arranged so as to oppose said first substrate; a liquid crystal layer interposed between said first substrate and said second substrate; a first electrode member provided on said first substrate, said first electrode member being provided with a comb-tooth-like portion; a second electrode member provided on said first substrate and having an interior corner portion opposing said comb-tooth like portion so as to generate an electric field between said first electrode member and said second electrode member; a protruded electrode member branched from adjacent to a tip end portion of said comb-tooth-like portion so as to form an L-shaped portion in an integrated planar shape; and a reverse rotation domain having boundaries defined by two legs of the L-shaped portion of the first electrode member and two sides of the interior corner portion of the second electrode member, wherein rotation of liquid crystal molecules in the liquid crystal layer is stabilized and in a same direction in an entirety of the reverse rotation domain and rotation is in an opposite direction beyond said boundaries while driving said liquid crystal layer.
