Abstract:
An array substrate for in-plane switching mode liquid crystal display device, comprising:a substrate having a plurality of pixel regions; a plurality of gate lines and a plurality of common lines in horizontal direction; a plurality of data lines crossing the gate line and the common line; a thin film transistor at a cross point of the gate line and the data line, the thin film transistor having a gate electrode, an active layer, a source electrode and a drain electrode; a pixel electrode having an extension portion, a vertical portion and a horizontal portion, the extension portion being extended from the drain electrode to the pixel region, the vertical portion being vertically extended from the extension portion and the horizontal portion being over the common line and being connected to the vertical portion; a common electrode having a plurality of vertical portions and a horizontal portion, the plurality of the vertical portions being vertically extended from the common line and arranged in an alternating pattern with the vertical portion of the pixel electrode, the horizontal portion connecting the plurality of the vertical portions into one portion; and an auxiliary line over the horizontal portion of the pixel electrode and being overlapped with the common line.
