Abstract
Provided is a TFT array substrate, which increases the area of a drain electrode of a TFT within a light-shielding zone to have the drain electrode overlapping a portion of a horizontal projection of a common electrode, wherein the drain electrode and the common electrode constitute a first storage capacitor and a pixel electrode and the common electrode constitute a second storage capacitor. The pixel electrode and the drain electrode are electrically connected and thus are of the same potential. The first storage capacitor and the second storage capacitor are connected in parallel and collectively form a storage capacitor such that the storage capacitor has a capacity that is equal to the sum of capacities of the first storage capacitor and the second storage capacitor, whereby, without reducing aperture ratio, the capacity of the storage capacitor is increased, crosstalk and image sticking are alleviated, and product display quality is enhanced.
