    摘要： A gate signal line drive circuit whose power consumption is reduced, is provided. In the gate signal line drive circuit having plural basic circuits outputting respective gate signals, each basic circuit includes a high voltage application switching element to which a first basic clock signal having high voltage in a signal high period is input, a low voltage application switching element that turns on at timing starting a signal low period, and outputs a low voltage, and a first low voltage application on control element having an input terminal to which a second basic clock signal subsequent to the first basic clock signal is input, and which turns on according to the signal high period, and outputs the voltage of the second basic clock signal to the control terminal of the low voltage application switching element.

    摘要： A liquid crystal display device includes a TFT substrate and a counter substrate with liquid crystal sandwiched therebetween. The TFT substrate has scanning lines 10 extending in a first direction and arrayed in a second direction and video signal lines 20 extending in the second direction and arrayed in the first direction. The TFT substrate has a display area 500 in which TFT pixels are arrayed in a matrix pattern, and a frame area 600 surrounding the display area. In the frame area 600, common bus wires 521 are formed in the same layer and with the same material as the video signal lines 20 and are impressed with a common voltage. Dummy TFTs are formed in a layer under the common bus wires 521. The scanning lines 10, extending over the frame area 600, are divided outside the display area and are interconnected by bridging wires 170.
