Film transistor array base plate

The invention discloses a film transistor array base plate which comprises a base plate, a plurality of electrode wires, a plurality of connection pads and a panel tester, wherein the base plate is provided with a display area and a peripheral circuit area, and the peripheral circuit area is provided with a terminal area and a frontal border area between the terminal area and the display area. The electrode wire is arranged in the display area and extends into the peripheral circuit area. The connection pads are arranged in the terminal area, and every electrode wire is electrically connected with a corresponding connection pad. The panel tester is arranged in the frontal border area, and electrically connected with the electrode wire. The panel tester comprises a short circuit rod and a plurality of switch elements, wherein the switch elements are electrically connected with the short circuit rod and the electrode wire. Because the panel tester is arranged in the frontal border area, the margin of line layout can be improved.
