Abstract

A semiconductor device is provided that includes wiring patterns on a substrate formed of an organic insulating film, and a semiconductor chip mounted on the substrate. A liquid crystal display panel and a PW board are electrically connected to each other with an anisotropic conductive adhesive. At least one surface of the insulating film is treated with a silicon coupling material. The silicon coupling material contains silicon (Si) at a surface element density of 0.5 atomic percent to 12.0 atomic percent on a surface of the insulating film.
