<p>The present invention provides a TFT-LCD array substrate, in which an additional second storage capacitor is introduced to satisfy the capacitance requirement. The second storage capacitor is formed by a first conductive layer, a second conductive layer, and a second insulating layer disposed between the first conductive layer and the second conductive layer, wherein the first conductive layer and the second conductive layer are respectively electrically connected, inside the pixel unit, to the potential of the transparent common electrode and that of the pixel electrode, that is, the first conductive layer and the second conductive layer that form the second storage capacitor is not required to extend across the entire pixel unit in order to be connected to the potential outside the pixel unit, but are merely required to be electrically connected to the potential of the transparent common electrode and that of the pixel electrode, respectively, inside the pixel unit. Thereby, under the condition that the capacitance is satisfying, the size of the second conductive layer are reduced, that is, the aperture ratio of the pixel unit is increased, so that the pixel unit has both a relatively large capacitance and a relatively high aperture ratio.</p> |
