摘要： In a liquid crystal display device having a repair line for replacing a signal line disconnected in a display area thereof and extended from one side thereof to another side thereof opposite to the one side thereof, there is provided a signal amplifier on a circuit board arranged at the one side thereof. Since the circuit board supplies control signals to a signal driver circuit which outputs a video signal or the like to be transferred by the repair line toward another side of the liquid crystal display device, the video signal can be amplified by the signal amplifier before its waveform is deformed on its way through the repair line. Therefore, the video signal can be supplied to a part of the disconnected signal line at the another side of the liquid crystal display device by preventing the video signal from being deformed and delayed.
