Abstract

A light-emitting display device includes an element-formation substrate and a plurality of pixels. The element-formation substrate includes a first barrier film and a second barrier film provided on a substrate, the first barrier film and the second barrier film being provided in the stated order from the substrate and suppressing ingress of moisture. The plurality of pixels is provided on the element-formation substrate. The element-formation substrate further includes an organic part that fills a crack occurred in the first barrier film, or that is attached around a part of a metallic foreign substance protruding from the first barrier film.

Claims (20)

1. A light-emitting display device, comprising:

an element-formation substrate including a first barrier film and a second barrier film provided on a substrate, the first barrier film being provided on and in direct contact with the substrate and the second barrier film being provided on an in direct contact with the first barrier film in the stated order from the substrate and suppressing ingress of moisture; and

a plurality of pixels provided on the element-formation substrate,

the element-formation substrate further including an organic part that fills a crack occurred in the first barrier film, or that is attached around a part of a metallic foreign substance, the part of the metallic foreign substance protruding from the first barrier film.

2. A light-emitting display device, comprising:

an element-formation substrate including a first barrier film and a second barrier film provided on a substrate, the first barrier film and the second barrier film being provided in the stated order from the substrate and suppressing ingress of moisture; and

a plurality of pixels provided on the element-formation substrate,

the element-formation substrate including an organic layer that fills a crack occurred in the first barrier film, and that covers a part of a metallic foreign substance, the part of the metallic foreign substance protruding from the first barrier film, the organic layer being provided between the first barrier film and the second barrier film, and the organic layer having a thickness smaller than a thickness of the first barrier film.

3. The light-emitting display device according to claim 2 ,

wherein the organic layer is provided at a region that is opposed to each of the plurality of pixels.

4. The light-emitting display device according to claim 1 ,

wherein the substrate comprises any one of polyimide, polyethylene terephthalate, polyether sulfone, polyethylene naphthalate, or polycarbonate.

5. The light-emitting display device according to claim 1 ,

wherein the first barrier film comprises any one of SiO 2 , SiN, SiON, Al 2 O 3 , or SiO.

6. The light-emitting display device according to claim 1 ,

wherein the first barrier film comprises a stacked film including two or more selected from the group consisting of SiO 2 , SiN, SiON, Al 2 O 3 , and SiO.

7. The light-emitting display device according to claim 3 ,

wherein the organic layer has an island shape.

8. The light-emitting display device according to claim 1 ,

wherein a top part of the metallic foreign substance is in contact with the second barrier film.
