A liquid crystal display device of an in-plane switching mode and a method for manufacturing the same are disclosed. The liquid crystal display device of an in-plane switching mode includes gate lines and data lines which cross each other on a substrate to define pixel regions, thin film transistors which are formed at crossing portions of the gate lines and the data lines, first common lines formed on the same layer as the gate lines, first electrode fingers which have a plurality of diverged first fingers and include L-shaped protruded patterns at one ends of the first fingers in the pixel regions, and second electrode fingers which have second fingers formed alternately with the first fingers and include |-shaped patterns at one ends of the second fingers in the pixel regions, wherein the L-shaped protruded patterns and the |-shaped patterns overlap partly with the first common lines.
