    • A circuit panel includes an array substrate in which a scanning line is formed as a capacitive load and first and second scanning line drivers connected to the scanning line in order to commonly drive the scanning line. Each of the first and second scanning line drivers includes first and second switching circuits connected in series between first and second power terminals to selectively output one of the potentials of the first and second power source terminals as a control signal, and an output buffer for setting the potential of the scanning line in accordance with the control signal. The driving abilities of the first and second switching circuits are uneven.

    • 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.
    • 改进采样开关到信号线驱动电路200内的视频总线的连接点的布置,使得提供有相对于预定参考电位的正极性视频信号的视频总线(SVn1至SVn6)的连接点和视频总线(SVp1 提供给模拟开关(SWn11〜SWn22,SWp11〜SWp22)的负极性视频信号的SVp6在视频总线的延伸方向上形成大致对称的图形。 由于属于开关对的连接布线的长度总和及其总电阻值在所有开关对中变得基本相等,所以信号线电位中的移位量的有效值基本上变平。 因此,这里提供了一种内置液晶显示装置的驱动电路,其实现了通过多个视频总线向视频信号提供视频信号时可能出现的诸如条纹成像缺陷之类的成像质量消除噪声。
