Abstract

A display device includes contact holes opened in an insulating film outside of a display area in which pixels are arranged, and having a conductive film exposed in bottom portions, a first metal film formed to cover the contact holes and come in contact with the conductive film of the bottom portions, and a transparent conductive film formed on the first metal film.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A display device, comprising:
 a display area in which pixels are arranged on a substrate; and a frame area that surrounds the display area,   wherein the display area includes:   pixel circuits arranged for the respective pixels;   an insulating film formed on the pixel circuits;   pixel electrodes each connected to the pixel circuit through a through-hole formed in the insulating film;   an organic layer arranged on the pixel electrodes, and including a light emitting layer; and   a transparent conductive film arranged on the organic layer,   wherein the frame area includes:   a conductive film;   contact holes opened in the insulating film covering the conductive film, and continuously arranged from the display area to the frame area, and exposing the conductive film at bottom portions thereof; and   a first metal film formed to cover the contact holes, and come in contact with the conductive film at the bottom portions, and   wherein the transparent conductive film is continuously arranged from the display area to the frame area, and formed on the first metal film.   
     
     
         2 . The display device according to  claim 1 ,
 wherein the transparent conductive film comprises an electrode that covers the overall display area.   
     
     
         3 . The display device according to  claim 1 ,
 wherein the first metal film is formed only on the frame area.   
     
     
         4 . The display device according to  claim 1 ,
 wherein the first metal film covers the overall display area together with the transparent conductive film.   
     
     
         5 . The display device according to  claim 1 , further comprising:
 a second metal film formed on the transparent conductive film so as to cover the overall display area.   
     
     
         6 . The display device according to  claim 1 ,
 wherein the contact holes are discretely formed in a plurality of places outside of the display area.   
     
     
         7 . The display device according to  claim 1 ,
 wherein the contact holes are formed outside of one of two pairs of opposed sides forming a rectangle of the display area.   
     
     
         8 . The display device according to  claim 1 ,
 wherein the pixels formed in the display area each have an organic light emitting layer that emits light by itself.
