のである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a liquid crystal display device that is widely used for displaying various characters or graphics, and particularly relates to a liquid crystal display device in which metal wiring is provided on a substrate such as glass that constitutes a liquid crystal display element. The present invention relates to a metal wiring arrangement structure of a so-called step-on-glass type liquid crystal display device in which a liquid crystal driving element is directly connected to the metal wiring arrangement structure.

続し配置していた。Conventionally, this type of liquid crystal display device has been disclosed, for example, in Japanese Patent Application Laid-Open No. 56-5
As shown in Japanese Patent No. 0368, generally, a plurality of metal wirings connected to display electrodes are formed on a glass substrate constituting a liquid crystal display element, and bonding pads are provided on these metal wirings. An LSI element for driving a liquid crystal was connected and arranged on the padding pad by wire bonding.

あシ、その修理技術も限定されていた。However, in liquid crystal display devices configured in this way, the mounting position of the LSI element is different for each liquid crystal display device, so the expandability of the LSI element is low, and the LSI element may fail. It was difficult to repair it next time, and the repair techniques were also limited.

置を提供することにある。Therefore, the present invention has been made in view of the above circumstances, and its purpose is to provide a liquid crystal display device that can be easily repaired in the event that the L8I element breaks down. . Another object of the present invention is to provide a liquid crystal display device in which other circuit boards can be mounted without changing the metal wiring.
このような目的を達成するために本発明は、複数本の金
属配線を、ＬＳＩ素子周縁部を除き絶縁性基板端縁から
一定のピッチで平行配置したものである。In order to achieve such an object, the present invention is such that a plurality of metal wirings are arranged in parallel at a constant pitch from the edge of an insulating substrate except for the peripheral edge of an LSI element.
