Patent ID: 8390194

Claim:
A flat panel display device comprising: a glass substrate; a metal encapsulation substrate disposed facing the glass substrate; a light-emitting unit disposed between the glass substrate and the metal encapsulation substrate; and a sealing unit disposed around the light emitting unit to adhere the glass substrate to the metal encapsulation substrate, the sealing unit comprising: a first sealant disposed around the light-emitting unit disposed on the metal encapsulation substrate; and a second sealant coated on the first sealant, wherein the first sealant and the second sealant both directly contacting the glass substrate and the metal encapsulation substrate, the second sealant directly contacting substantially an entirety of the first sealant surface that is not directly contacting the metal encapsulation substrate and the glass substrate, the first sealant coming into direct contact with a larger surface area of the metal encapsulation substrate than with the glass substrate, and the second sealant coming into direct contact with a larger surface area of the glass substrate than with the metal encapsulation substrate.
