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.

摘要： A bidirectional shift register capable of performing a stable shift operation in both directions and an image display device using the same are provided. In forward shift operation, when reference point N1 is at H level, (n+4)-th unit register circuit as a rear stage of the bidirectional shift register outputs pulse G(n+4) in synchronization with clock pulse V (n+4) inputted to (n+4)-th unit register circuit. A backward direction trigger signal VSTB is generated not only at the time of start of backward shift, but also, for example, in period (time t4 to t5) of one-phase clock immediately after G(n+4) is outputted in vertical blanking interval of the forward shift. The backward direction trigger signal VSTB is inputted to gate of a transistor provided to set reference point N1 of (n+4)-th unit register circuit to H level at the time of start of the backward shift.
