    • To provide a liquid crystal display capable of implementing a symmetrical frame and a narrower frame without lowering drive capability of a common drive circuit.[Solution]A liquid crystal display substrate 10 has a data driver circuit 2 and a gate driver circuit 3 for driving the liquid crystal display integrated thereon together with a common drive circuit 4, where common voltages VCOMH and VCOML are applied from the outside through a pad. The gate driver circuit 3 is placed to be adjacent to one of the four terminals of the liquid crystal display. The common drive circuit 4 is placed to be adjacent to the terminal opposite to where the gate driver circuit 3 is placed and as close to the pad as possible while having almost the same width as the area of the gate driver circuit 3. The pad close to where the common drive circuit 4 is placed is used as the pad for applying the common voltages VCOMH and VCOML.
    • 提供能够实现对称框架和较窄框架而不降低公共驱动电路的驱动能力的液晶显示器。 [解决方案]液晶显示基板10具有数据驱动电路2和用于驱动集成在其上的液晶显示器的栅极驱动电路3以及公共驱动电路4,其中公共电压VCOMH和VCOML从外部通过一个 垫。 栅极驱动器电路3被放置成与液晶显示器的四个端子中的一个相邻。 公共驱动电路4被放置成与栅极驱动器电路3相对的端子相邻,并且尽可能靠近焊盘,同时具有与栅极驱动器电路3的面积几乎相同的宽度。焊盘闭合 使用公共驱动电路4的位置作为用于施加公共电压VCOMH和VCOML的焊盘。
