Display panel substrate and display panel

A display panel substrate comprising:

• a plurality of electrode terminals for connecting an external circuit board;
• a plurality of drawing lines each electrically continuous to the plurality of electrode terminals;
• an interlayer insulating film covering the plurality of drawing lines;
• conductive material films each superimposed on the plurality of electrode terminals and each electrically continuous to the plurality of electrode terminals;
• and
• conductive material films each superimposed on the plurality of drawing lines while interposing the interlayer insulating film and each electrically continuous to the plurality of drawing lines,
• wherein the plurality of drawing lines are parallel to one another, and
• the conductive material films each superimposed on the plurality of electrode terminals and the conductive material films each superimposed on the plurality of drawing lines while interposing the interlayer insulating film are separate in a peripheral portion of the interlayer insulating film, and the conductive material films each superimposed on the adjacent plurality of drawing lines while interposing the interlayer insulating film are separate.
