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.

摘要： A liquid crystal display device used in miniaturized portable equipment includes a distribution circuit to cope with a high-definition multi-grayscale display. A distribution circuit distributes an output of a drive circuit to a plurality of video signal lines within one scanning period, the distribution circuit being divided into a plurality of distribution circuits, and control signals being supplied to each distribution circuit from both end portions of each distribution circuit. When an output part of the drive circuit is configured such that a high withstand-voltage output amplifier and a low withstand-voltage output amplifier are alternately connected with the distribution circuit, a master function and a slave function are imparted to the drive circuit so as to allow the drive circuit to cope with odd-numbered outputs.
