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.
Claims7
A display device comprising:
- a substrate having a display area in which a plurality of pixels are arranged, each of the plurality of pixels including a pixel circuit and a pixel electrode, each of the plurality of pixels including an organic layer on the pixel electrode, the organic layer including a light emitting material, the substrate having a frame area surrounding the display area;
- an insulating film on the pixel circuit, the insulating film having a through-hole through which the pixel electrode is connected to the pixel circuit;
- and
- an electrode film entirely covering the display area and extending to the frame area,
- wherein the frame area includes a conductive film covered by the insulating film, the insulating film having contact holes, the contact holes exposing the conductive film at bottom potions of the contact holes,
- wherein the electrode film includes a metal layer and a transparent conductive layer on the metal layer, and the metal layer contacts the conductive film through each of the contact holes, and
- wherein the transparent conductive layer covers the display area and the contact holes.
