A thin film transistor array substrate including a substrate, scan lines, data lines, thin film transistors, pixel electrodes, common lines and a patterned upper electrode is provided. The scan lines and the data lines are disposed over the substrate to define pixel areas. Each thin film transistor is disposed within one of the pixel areas and is driven by one of the scan lines and data lines. Each pixel electrode is disposed within one of the pixel areas and is electrically connected to one of the thin film transistors. Common lines are disposed over the substrate such that a portion area of each pixel electrode is located above one of the common lines. The pattern upper electrode includes sub-upper electrodes disposed between the pixel electrode and the common line. The sub-upper electrodes are electrically connected to the pixel electrodes for coupling with the common lines to form a storage capacitor.
