Substrate for display and liquid crystal display utilizing the same

Abstract

The invention provides a substrate for a display which can be easily repaired even when there are problems such as inter-layer shorting attributable to invasion of static electricity. The substrate has a first wiring section disposed in a display area thereof and formed so as to outwardly extend from the inside of the display area. The substrate also has a second wiring section formed such that it intersects the first wiring section outside the display area on the substrate with an insulation film interposed between them. The substrate further has an opening formed in the second wiring section at least in a region thereof overlapping the first wiring section intersecting the same. Further, the substrate has overlapping portions formed at two ends of the opening where the first and second wiring sections overlap each other with the insulation film interposed between them.

1 . A substrate for a display comprising:
 a first wiring section formed so as to outwardly extend from the inside of a display area on a substrate;   a second wiring section formed so as to intersect the first wiring section outside the display area with an insulation film interposed between them;   an opening formed in the second wiring section at least in a region thereof overlapping the first wiring section intersecting the second wiring section; and   overlapping portions formed at two ends of the opening where the first and second wiring sections overlap each other with the insulation film interposed between them.   
   
   
       2 . A substrate for a display according to  claim 1 , wherein the opening is formed in the direction in which the first wiring section extends. 
   
   
       3 . A substrate for a display according to  claim 1 , wherein the opening is formed in the direction in which the second wiring section extends. 
   
   
       4 . A substrate for a display according to  claim 2 , wherein a plurality of the openings is formed. 
   
   
       5 . A substrate for a display according to  claim 3 , wherein a plurality of the openings is formed. 
   
   
       6 . A substrate for a display according to  claim 1 , further comprising a third wiring section formed across the opening and stacked on the second wiring section with a second insulation film interposed therebetween. 
   
   
       7 . A substrate for a display according to  claim 6 , wherein the third wiring section has a connection part electrically connected to the second wiring section. 
   
   
       8 . A substrate for a display according to  claim 6 , wherein a plurality of the third wiring sections are formed. 
   
   
       9 . A substrate for a display according to  claim 1 , wherein the second wiring section comprises a storage capacitor common electrode section commonly connected to each of a plurality of storage capacitor elements formed in the display area. 
   
   
       10 . A substrate for a display according to  claim 1 , further comprising a plurality of anti-ESD sections disposed on the substrate and connected to respective bus lines constituting the first wiring section, wherein the second wiring section comprises one anti-ESD common wiring section which is commonly connected to each of the plurality of anti-ESD sections. 
   
   
       11 . A substrate for a display according to  claim 1 , further comprising a horizontal electric field forming opposite electrode disposed for forming a horizontal electric field between a pixel electrode in the display area and itself and formed in association with the pixel electrode, wherein the second wiring section comprises one common electrode section for opposite electrodes which is commonly connected to each of a plurality of the horizontal electric field forming opposite electrodes. 
   
   
       12 . A display comprising a substrate having a plurality of bus lines, wherein a substrate for a display according to  claim 1  is used as the substrate.
