    • In a liquid crystal display device comprising, first and second substrates and a liquid crystal layer sealed therebetween constituting a panel, a first plurality of electrodes extending in a first direction in the panel, a second plurality of electrodes being extending in the second direction transverse to the first direction in the panel, a first printed circuit board having a laminated structure of a plurality of printed circuit layers and disposed at a periphery of the panel extending along the second direction, and a plurality of first driver circuits juxtaposed between the first printed circuit board and the panel in the second direction and having a plurality of electrical contacts with the first printed circuit board on its first printed circuit layer from its upper surface so as to supply the at least one clock signal in parallel to the respective first driver circuits, the present invention disposes a transmitting line for the at least one clock signal on one of the printed circuit layers of the a first printed circuit board closer to its upper surface than a center of its laminated thickness. By this configuration, the present invention reduce parasitic capacitance occurring along a signal path of the at least one clock signal sufficiently so as to obtain a high-quality liquid crystal display without flicker caused by miscounting of pixel clock signals or like.
    • 在一种液晶显示装置中,包括第一和第二基板和密封在其间的液晶层构成面板,第一多个电极沿面板的第一方向延伸,第二多个电极沿第二方向横向于 面板中的第一方向,具有多​​个印刷电路层的叠层结构并且设置在沿着第二方向延伸的面板的周边的第一印刷电路板,以及并列在第一印刷电路之间的多个第一驱动电路 板和面板在第二方向上并且在其第一印刷电路层上与其第一印刷电路层上的第一印刷电路板具有多个电触点,以便将至少一个时钟信号并行地提供给相应的第一驱动器电路, 本发明在打印的ci之一上配置用于至少一个时钟信号的传输线 第一印刷电路板的比其层叠厚度的中心更靠近其上表面的电路层。 通过该结构,本发明能够充分地减少沿着至少一个时钟信号的信号路径发生的寄生电容,以获得高质量的液晶显示器,而不会由于像素时钟信号等的错误计数而产生闪烁。
