Source driver, electro-optical device, projection-type display device, and electronic instrument

Abstract

A source driver that drives a source line of an electro-optical device based on (j+k)-bit (j and k are natural numbers) grayscale data includes 2j grayscale signal lines, a grayscale voltage select circuit that outputs two grayscale voltages among 2j grayscale voltages supplied through the 2j grayscale signal lines, and a source line driver circuit that outputs a grayscale voltage corresponding to lower-order k-bit data of the grayscale data from the source line driver circuit to the source line, the grayscale voltage output to the source line being a voltage among voltages between the low-potential-side grayscale voltage and the high-potential-side grayscale voltage output from the grayscale voltage select circuit to the source line driver circuit.
