Abstract:
A semiconductor device, comprising plural lines of metal wires formed on a substrate each having a connection terminal positioned at the end of said substrate for connecting to an external driving circuit for applying voltage independently to every pixel electrode:wherein each of said metal wires at the position of said connection terminal is provided with an interterminal anti-short-circuiting pattern comprising conductive island and recess(es) located around said island;wherein the surface of said metal wire except at least a portion of said island but including the inside of said recess(es) thereon are covered with a protective insulating film;wherein a contact hole is formed of the uncovered portion with said protective insulating film on said island;wherein a bottomed pool arriving at said recess is provided through said protective insulating film adjacent to said contact hole; andwherein a transparent conductive film is deposited on the surface of said protective insulating film, including inside of said contact hole and said bottomed pool.
