The present invention discloses a TFT array substrate and a display panel. Multiple pixel electrodes structured with at least one domain are arranged in each pixel area, and the angle/angles of at least one deflection in the same-sided deflections of the pixel electrodes of the same domain in the pixel area in the direction parallel to the initial arrangement direction of liquid crystal not driven by a voltage to rotate is different from the angles of other deflections. Through the design of different deflection angles of the pixel electrodes of the same domain, even under a low gray scale, since the rotating angles of liquid crystal molecules driven by different pixel electrodes are different, the inner parts of the liquid crystal molecules driven by the pixel electrodes may be relatively completely compensated.
