Abstract:
1. An in-plane switching mode liquid crystal display device, comprising: a first substrate including a plurality of pixel regions; a plurality of gate lines on the first substrate; a plurality of data lines on the first substrate and crossing the gate lines to define the plurality of pixel regions; a common line on the first substrate and parallel to the gate line; a thin film transistor in each pixel region and connected to one of the plurality of gate lines and one of the plurality of data lines; a first common electrode and a pixel electrode on the first substrate and alternating with each other in each pixel region, each of the first common electrode and the pixel electrode including a lower layer and an upper layer; second and third common electrodes respectively extending from the common line along the data line; a conductive pattern on the first substrate and overlapping the data line and the second and third common electrodes, wherein the conductive pattern is formed of the same material as the first common electrode; a second substrate facing the first substrate; a color filter layer including red, green and blue color filter patterns and on the second substrate, the red, green and blue color filter patterns corresponding to each pixel region; and a liquid crystal layer between the first and second substrates, wherein at least two of the red, green and blue color filter patterns overlap each other at a boundary of the pixel regions, wherein the lower layer is made of molybdenum-titanium alloy (MoTi), and the upper layer is made of a transparent conductive material or copper nitride, and wherein the pixel electrode and the first common electrode are located between the second and third common electrodes.
