Abstract:
1. A liquid crystal display, comprising: a first substrate and a second substrate processed for vertical alignment; a liquid crystal material having a negative dielectric constant anisotropy and being sandwiched between the first and second substrates; a light-shielding matrix formed on the first substrate; a plurality of parallel gate lines formed on the second substrate; a plurality of parallel data lines perpendicular to the gate lines, wherein the gate lines and the data lines are arranged to form a matrix of pixel regions with each of the pixel regions defined by two adjacent gate lines and two adjacent data lines; a pixel electrode in each of the pixel regions, the pixel electrode having first edges parallel to the gate lines and second edges parallel to the data lines; an array of protrusions each having a main body and a plurality of branches on the first substrate, the main bodies of the protrusions having zigzag patterns arranged in parallel to one another; and an array of slits provided on the pixel electrodes, the slits and the main bodies of the protrusions being arranged alternately; wherein all of the branches of the protrusions are formed at positions facing the second edges of the pixel electrodes in a manner that the angle between the branches of the protrusions and the slits is at most 45 degrees; and wherein the second edges of the pixel electrodes have a plurality of recesses arranged in a sawtooth pattern and formed outside the branches of the protrusions.
