摘要

1. The substrate of the active matrix, containing:! a plurality of first interconnects formed parallel to each other in the display area; ! a plurality of second interconnects formed parallel to each other, and so as to intersect the plurality of first interconnects in the display area; ! a plurality of first contact pins located in a pin terminal area; ! a plurality of second contact terminals located in the area of the location of the contact terminals; ! a plurality of first selecting interconnects connecting a plurality of first interconnects and a plurality of first contact terminals, respectively, and! a plurality of second interconnect selectors connecting a plurality of second interconnects and a plurality of second contact terminals, respectively! wherein the plurality of first select interconnects includes a plurality of third select interconnects and a plurality of fourth select interconnects, wherein the third select interconnects are formed in a layer identical to the layer in which the first interconnects are formed, at least a portion of the fourth interconnects are formed in a layer other than the layer in which the first interconnects are formed with the insulating material interposed between them, wherein the third interconnects are selected and the fourth interconnects are selected I formed alternately per interconnection in the peripheral interconnect, which is different from the display area and the siting of terminals, and! the substrate of the active matrix contains:! a plurality of first connecting interconnects connected to a plurality of first contacts
