Patent ID: 7227606

Claim:
A liquid crystal display device, comprising: a first substrate and a second substrate for sandwiching a liquid crystal having a negative dielectric constant anisotrophy, and molecules of said liquid crystal being generally vertical to said first and second substrates when no voltage is applied; said first substrate including first domain regulating means for regulating azimuths of orientations of said liquid crystal molecules when a voltage is applied to said liquid crystal, said azimuths of orientation being defined as angles of alignment of said molecules in a plane generally parallel to planes of said first and second substrates; said second substrate including second domain regulating means for also regulating azimuths of said liquid crystal when a voltage is applied; said first domain regulating means including protrusions projecting into said liquid crystal, said protrusions being made of dielectric: and said azimuths of orientation respectively aligning according to a shape of a near one of said protrusions seen looking vertically to said planes of said substrates.
