    • In order to reduce the scale of drive ICs and to prevent uneven display in signal line selective drive, in this liquid crystal display device, for each group in which one video output line corresponds to N signal lines, the signal line is switched and connected to the video output line via an analog switch ASW. Thus, the number of the video output lines is reduced to 1/N. Moreover, as to an Lth scan line, for each of the groups, a signal line to which a video signal having its polarity inverted between an L-1th scan line and the Lth scan line is supplied is selected first and a signal line to which a video signal having its polarity not inverted is supplied is selected later. Thus, a video signal in which a polarity is not inverted and no potential change occurs is supplied to the signal line later.
    • 为了减小驱动IC的规模并防止信号线选择性驱动中的不均匀显示,在该液晶显示装置中,对于其中一个视频输出线对应于N条信号线的每组,信号线被切换并连接到 视频输出线通过模拟开关ASW。 因此,视频输出线的数量减少到1 / N。 此外,对于第L扫描线,对于每个组,首先选择其中提供其在第L-1扫描线和第L扫描线之间具有极性反转的视频信号的信号线和信号线, 稍后选择其反相极性的视频信号被提供。 因此,稍后在信号线上提供极性不反转并且没有发生电位变化的视频信号。

    • Arrangement of connection points of sampling switches to video bus lines within a signal line drive circuit 200 is improved such that connection points of video buses (SVn1 to SVn6) supplied with positive-polarity video signals relative to a predetermined reference potential and video buses (SVp1 to SVp6) supplied with negative-polarity video signals to analog switches (SWn11 to SWn22 and SWp11 to SWp22) make substantially symmetric patterns in the extending direction of the video buses. Since the sum of lengths of connection wirings belonging to a switch pair and their total resistance value becomes substantially equal in all switch pairs, the effective vales of shift amounts in signal line potentials are substantially flattened. Therefore, here is provided a drive circuit built-in liquid crystal display device realizing a good imaging quality removing noise such as stripe-shaped imaging defects which may occur when video signals are supplied to analog switches through a plurality of video buses.
