  • Publication number: 20110091694
    Abstract: The present invention is an electrode of an electric device, having a portion at which a pattern is formed using a photosensitive paste, and a portion at which a pattern is formed using a transfer method. Described is a method in which migration at an electrode portion is curtailed by using a photosensitive paste to form a pattern at areas where electrode width is comparatively large, and by forming a pattern using a transfer method at areas where electrode width becomes narrower.
