Abstract
A thin film transistor array substrate includes: a substrate on which a thin film transistor and a storage capacitor are formed. The storage capacitor includes a first electrode plate formed on the substrate, a gate isolation layer or an etching stopper layer formed on the first electrode plate, and a second electrode plate formed on the gate isolation layer or the etching stopper layer. The etching stopper layer may be formed on the gate isolation layer, of which one is partially etched and removed such that there is only one of the gate isolation layer and the etching stopper layer existing between the two electrode plates of the storage capacitor so as to reduce the overall thickness of the isolation layer of the storage capacitor. Thus, the capacitor occupies a smaller area and a higher aperture ratio may be achieved.
