Patent ID: 8687159

Claim:
A liquid crystal display device of an in-plane switching mode comprising: a substrate; gate lines and data lines which cross each other on the substrate to define pixel regions; thin film transistors which are formed at crossing portions of the gate lines and the data lines; first electrodes which have a plurality of first fingers and include L-shaped protruded patterns at one end of each of the first fingers in the pixel regions, wherein the L-shaped protruded patterns include first edge portions extended from the first fingers and second edge portions inclined to the first edge portions at 100Ëœ115 degrees, and the second edge portion is parallel to the gate lines, wherein the first fingers are formed as a single body with at least one common line; second electrodes which have second fingers formed alternately with the first fingers and include |-shaped patterns at one end of each of the second fingers in the pixel regions, wherein at the one end of each of the second fingers, the |-shaped pattern is extended toward the at least one common line to overlap with adjacent L-shaped protruded patterns of a left side, and â€œâˆ’â€ shaped patterns are further extended from ends of the |-shaped patterns to overlap with the L-shaped protruded patterns of a right side, wherein the |-shaped patterns and the â€œâˆ’â€ shaped patterns are formed in a same identical shape with the L-shaped protruded patterns of the first fingers to improve uniformity of a direction of electric field; and wherein the at least one common line is formed on a same layer as the gate lines, wherein the first electrodes are made of metal of the same layer as the gate lines, and the second electrodes are formed of a transparent metal layer; wherein the L-shaped protruded patterns have a shape protruded from the at least one common line the L-shaped protruded patterns made of the metal are separated each other, and each second edge portion overlaps with a part of an adjacent |-shaped pattern made of the transparent metal layer; wherein the at least one common line has a reduction portion to open the transparent |-shaped patterns at each end of each of the second fingers; wherein the reduction portion and the second edge portion are alternately formed with respect to the at least one common line; wherein a crossing portion of each reduction portion and each of the corresponding second edge portion is at each of the corresponding |-shaped pattern, and wherein the â€œâˆ’â€ shaped patterns of the second fingers and the second edge portion of the first fingers are identical portions that are disposed on a same line parallel to the gate line.
