Abstract
In a display device, under a analog display mode, an analog image signal amplified by an analog amplifier is outputted to a liquid crystal display panel. Under an digital display mode, after being processed by a signal processing circuit, the digital image signal is outputted to the liquid crystal display panel through a DA converter and an amplifier. For writing a 'white' image signal, the signal processing circuit converts the input digital signal so that all bits of the signal are a '1.' Also, for writing a 'black' image signal, the signal processing circuit converts the input digital signal so that all bits of the signal are a '0.'
