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

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.
