て説明する。2. Description of the Related Art In recent years, liquid crystal display devices are being replaced by CRTs in various devices as thin, lightweight and low power consumption devices. Furthermore, with the increase in the number of pixels of the liquid crystal panel, it has become necessary to increase the density when connecting the liquid crystal driving IC to the electrode surface of the liquid crystal panel. COG is one of the mounting methods for high density. This is because the liquid crystal driving IC is mounted on the first glass substrate of the liquid crystal panel, and the liquid crystal driving IC is mounted.
This is a method of electrically connecting the output terminal of C and the electrode on the first glass substrate via a conductive substance. According to the COG mounting method, indium tin oxide (ITO) electrode wiring, which is a transparent conductive film on glass, can be formed in a fine pattern. Hereinafter, the mounting substrate will be described as a glass substrate, and the mounting method will be described as COG.
