Patent ID: 8542335

Claim:
A simple matrix type dot-matrix liquid crystal display element comprising: a first and a second transparent substrate disposed opposite to each other; two or more first transparent electrodes that are disposed on a face of the first transparent substrate, said face facing to the other substrate, and that are extended as a whole in a first direction; two or more second transparent electrodes that are disposed on a face of the second transparent substrate, said face facing to the other substrate, and that are extended as a whole in the perpendicular direction to said first direction; a first and a second vertical alignment film disposed on the opposed side of the first and the second transparent substrate to cover the first and the second transparent electrodes, respectively; a liquid crystal layer disposed between the opposed faces of the first and the second transparent substrate and having a negative dielectric constant anisotropy and a retardation of more than 450 nm; a first and a second viewing angle compensation plate disposed on the unopposed faces of the first and the second transparent substrate, respectively; and a first and a second polarizing plate disposed in a nearly crossed Nicols arrangement outside the first and the second viewing angle compensation plate, respectively; wherein: at least either of the first and the second vertical alignment film is treated by an alignment process in a second direction that contains a component of the first direction; each pixel formed by the first and the second electrode overlapping each other with said liquid crystal layer sandwiched in between have two or more sides that intersect with perpendiculars to said second direction; and in those portions that correspond to said pixels in said first transparent electrode, openings extending in said direction that contains a component of the first direction are aligned.
