An LCD array substrate includes a gate line, a data line, a thin film transistor, a pixel electrode and a storage line. The pixel electrode is formed in a unit pixel defined by the gate line and the data line and is electrically connected to the thin film transistor. The storage line includes a main storage line, a first sub storage line and a second sub storage line. The first sub storage line overlaps a first edge portion of the pixel electrode by a first length. The first sub storage line overlaps a second edge portion of the pixel electrode opposite to the first edge portion by the first length. This arrangement prevents a misalignment of the pixel electrode from causing a variation in kickback voltage, thereby improving display image quality.
