Abstract
Provided is a display device drive circuit capable of setting an optimum drive performance for each output amplifier without increasing the chip size. The display device drive circuit includes: at least two bias lines having different reference potentials; a selector that selects one of the bias lines based on a grayscale signal; and an output amplifier that is supplied with a reference potential of the one of the bias lines selected by the selector, generates a display signal, and supplies the display signal to a data line.
