Abstract
According to an embodiment, an array substrate for an LCD device includes a substrate; gate lines on the substrate along a first direction; data lines formed along a second direction and crossing the gate lines to define pixel regions; a common line between adjacent gate lines; a thin film transistor at each crossing point of the gate lines and the data lines; red, green and blue color filter patterns sequentially disposed in the pixel regions, respectively; a common electrode over each of the red, green and blue color filter patterns and connected to the common line; and a pixel electrode over the common electrode and connected to the thin film transistor, the pixel electrode overlapping the common electrode.
