Abstract

A display device having high reliability is provided. A frame of a display device is narrowed. A display device such as a liquid crystal display device includes a first substrate, a second substrate overlapping with the first substrate, a liquid crystal layer between the first substrate and the second substrate, a first sealant surrounding the liquid crystal layer between the first substrate and the second substrate, and a second sealant surrounding the first sealant, closing a gap between the first substrate and the second substrate, and extending to at least a side surface of the second substrate.

Claims

1. A display device comprising:

a first substrate;

a second substrate overlapping with the first substrate;

a liquid crystal layer between the first substrate and the second substrate;

a first sealant between the first substrate and the second substrate, the first sealant surrounding the liquid crystal layer; and

a second sealant surrounding the first sealant,

wherein the second sealant closes a gap between the first substrate and the second substrate, and

wherein the second sealant extends to at least a side surface of the second substrate.

2. The display device according to claim 1,

wherein the first sealant comprises an epoxy resin or an acrylic resin.

3. The display device according to claim 1,

wherein the second sealant comprises a frit glass.

4. The display device according to claim 1 further comprising a third sealant surrounding the second sealant.

5. The display device according to claim 4,

wherein the third sealant comprises any one of aluminum, copper, lead, and nickel.

6. An electronic device comprising a panel including the display device according to claim 1.
