    • An LCD having a plurality of test pads applied with a common voltage, covered with respective shielding conductor or located sufficiently far from pixels. A gate wire including pluralities of gate lines and test pads disconnected from the gate lines and located near one ends of the gate lines, and a common electrode wire including a plurality of common electrodes and a common electrode pad connected to the common electrode electrodes are formed on a substrate, and covered with a gate insulating film. A data wire and a pixel electrode wire are formed thereon and covered with a passivation film. The passivation film and the gate insulating film have contact holes exposing the test pads and the common electrode pad. A plurality of connecting members which are connected to the test pads and the common electrode pad through the contact holes are formed on the passivation film. Alternatively, the passivation film and the gate insulating layer have contact holes exposing only the common electrode pad, and a plurality of shielding members are provided on the passivation layer to be connected to the common electrode pad and to cover the test pads. Alternatively, the distance between the gate lines and the test pads is equal to or larger than twice the width of the pixel.
    • 一种LCD,其具有施加有公共电压的多个测试焊盘,覆盖有相应的屏蔽导体或位于足够远离像素的位置。 一种栅极线,其包括多条栅极线和测试焊盘,与栅极线断开并位于栅极线的一端附近,并且形成包括连接到公共电极电极的多个公共电极和公共电极焊盘的公共电极线 在基板上,并覆盖有栅极绝缘膜。 数据线和像素电极线形成在其上并被钝化膜覆盖。 钝化膜和栅极绝缘膜具有暴露测试焊盘和公共电极焊盘的接触孔。 通过接触孔连接到测试焊盘和公共电极焊盘的多个连接部件形成在钝化膜上。 或者,钝化膜和栅极绝缘层具有仅暴露公共电极焊盘的接触孔,并且在钝化层上设置多个屏蔽构件,以连接到公共电极焊盘并覆盖测试焊盘。 或者,栅极线和测试焊盘之间的距离等于或大于像素宽度的两倍。
