摘要： A driver circuit including a DA converting circuit that converts video data input from the outside to a grayscale voltage; an amplifying circuit that amplifies the grayscale voltage; and a switch circuit that selects the grayscale voltage output from the amplifying circuit and a predetermined voltage as a voltage that is output to the image line. When video data indicating a minimum grayscale, the switch circuit outputs the predetermined voltage to the image line, and when video data indicating a grayscale other than the minimum grayscale is input, the switch circuit outputs the grayscale voltage output from the amplifying circuit to the image line. The predetermined voltage allows a voltage of the pixel electrode and a voltage of the counter electrode after passage of the writing of the image voltage to be coincident with each other.
