The invention discloses a TFT array substrate, a liquid crystal display panel and a liquid crystal display. The TFT array substrate comprises a plurality of pixel electrodes, a first insulating layer and a plurality of compensation electrodes. The pixel electrodes are located in a pixel area, the pixel electrodes are in a bent strip shape and are arranged at intervals, the pixel area is divided into two domain areas by bending portions of the pixel electrodes, the first insulating layer is arranged on the pixel electrodes, the compensation electrodes are arranged on the first insulating layer and are arranged between the pixel electrodes, each compensating electrode is arranged between every two pixel electrodes, the compensating electrodes are in a bent strip shape, and the bending portions of the compensation electrodes are located at the connecting position of the two domain areas. According to the TFT array substrate, the liquid crystal display panel and the liquid crystal display, the area of the disclination area in a double-domain structure of the IPS and FFS mode is reduced, the display performance of the double-domain structure is improved, and the light penetration rate of the liquid crystal display is improved.
