Abstract
Conductive rubbing sludge generated by rubbing attaches to side portions of chip-on-glass (COG) terminals and terminal wiring lines and possibly causes short-circuiting (leakage) between adjacent terminal wiring lines via particles included in an anisotropic conductive film (ACF) which connects bumps of a semiconductor chip such as a driver IC to COG terminals. In the liquid crystal display device, each terminal wiring line connected to a COG terminal has a projecting part designed to generate an area not subjected to rubbing.
