Embodiments of the present invention discloses an array substrate of display device and a method for manufacturing the same, which can effectively restrain the interference by the signals over data lines with the modulation conducted by liquid crystal thereon, and improve light transmittance. The array substrate comprises: a pixel region defined by a gate line intersecting a data line. A thin film transistor, a pixel electrode, and a common electrode, which cooperates with the pixel electrode to form a multi-dimension electric field, are disposed in the pixel region. The pixel electrode is a slit-shaped electrode, and the common electrode is a plate-shaped electrode; or the pixel electrode is a plate-shaped electrode, and the common electrode is a slit-shaped electrode. An end of the plate-shaped electrode covers the data line, and a second insulating layer is disposed between a layer of the plate-shaped electrode and a layer of the data line.
