ABSTRACT:
A liquid crystal display mainly includes a first substrate and a second substrate processed for vertical alignment; a liquid crystal having a negative dielectric constant anisotropy and being sandwiched between the first and second substrates; an array of protrusions arranged in parallel to one another on the first substrate; and an array of slits provided on the pixel electrodes. The second substrate is provided with a plurality of gate lines, a plurality of data lines and a plurality of pixel electrodes. The pixel electrodes have first edges parallel to the gate lines and second edges parallel to the data lines. The protrusions have branches formed at positions facing the second edges of the pixel electrode in a manner that the angle included between the branches of the protrusions and the slits is kept at most 45 degrees.
