Abstract:
A liquid crystal display device comprising:a plurality of pixels adapted to be supplied with respective video signal voltages; and a plurality of video signal driver circuits which output respective output voltages and supply the output voltages to the plurality of pixels as the video signal voltages; wherein each of the plurality of video signal driver circuits includes: a pair of amplifier circuits which supply a respective one of the video signal voltages to one of the plurality of pixels, the pair of amplifier circuits including a first amplifier circuit including a first output terminal, a first input terminal, and a second input terminal, and a second amplifier circuit including a second output terminal, a third input terminal, and a fourth input terminal; a first connecting circuit switchable between a first connection in which an output voltage output from the first output terminal is input to the first input terminal as a reference voltage, and a second connection in which the output voltage output from the first output terminal is input to the second input terminal as a reference voltage; and a second connecting circuit switchable between a third connection in which an output voltage output from the second output terminal is input to the third input terminal as a reference voltage, and a fourth connection in which the output voltage output from the second output terminal is input to the fourth input terminal as a reference voltage.
