Abstract
A DA converter is provided with a select circuit that selects a predetermined number of gray scale reference voltages from a plurality of different gray scale reference voltages on a basis of display data corresponding to a plurality of different gray scale values, and an output circuit that outputs an output voltage corresponding to the gray scale values on a basis of the gray scale reference voltages selected by the select circuit. When the gray scale reference voltages corresponding to the selected gray scale values are substantially equal to the output voltage, the select circuit selects the gray scale reference voltages such that at least one of the gray scale reference voltages to be selected is different from the others.
