The invention provides a TFT array substrate structure. A patterned metal shielding layer (100) comprises a plurality of metal shielding blocks (101) and a metal narrow strip (102), wherein the plurality of metal shielding blocks (101) are arranged in an array form; the metal narrow strip (102) is connected with two adjacent metal shielding blocks (101); the metal shielding layer (100) and a common electrode (60) are connected to a common voltage signal (COM); aiming at each TFT (90), a pixel electrode (80) is in contact with a drain (92) of the TFT (90), so that the opposite overlapping parts of the pixel electrode (80) and the common electrode (60) form a first storage capacitor (Cst1); the opposite overlapping parts of the metal shielding layer (100) and the drain (92) and the pixel electrode (80) form a second storage capacitor (Cst2); the first storage capacitor (Cst1) and the second storage capacitor (Cst2) form a parallel relationship; the capacity of the storage capacitors can be increased; the metal shielding layer (100) is located in a shielding region; and the aperture ratio is not affected by improvement of the metal shielding layer (100).
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a TFT array substrate structure. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer Screens, etc., dominate the field of flat panel displays. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate) and the color filter substrate (ColorFilter, CF), and apply a driving voltage on the two substrates to control the rotation of the liquid cryst...
