Abstract
An electrode connecting device of a liquid crystal display element connects a transparent electrode terminal formed on a substrate constructed by a flexible film to an electrode terminal of a driving circuit and an external circuit through an anisotropic conductive film. The electrode connecting device has a protecting film formed on a surface of a connecting portion on which the transparent electrode terminal is formed. The protecting film can absorb stress applied to the transparent electrode at a thermal press-fixing time and can move conductive particles within the anisotropic conductive film. Both the electrodes are electrically connected to each other through the conductive particles within the anisotropic conductive film extending through the protecting film. The protecting film may be disposed on only the transparent electrode. A peripheral substrate portion around both the connected electrodes may be covered with another protecting film.
