PURPOSE: An organic electro-luminescence light emitting device is provided to increase strength of a sealant by using a buffer layer between a sealing cover and a substrate. CONSTITUTION: An organic electro-luminescence light emitting device includes a substrate(21), an organic field effect light emitter(22), a sealing cover(23), a humidity preventing unit(25), and a buffer layer(27). The organic field effect light emitter is formed on one side of the substrate and includes a first electrode, an organic layer, and a second layer laminated orderly thereon. The sealing cover is coupled with a sealant around the substrate and seals an inner space containing the organic field effect light emitter. The humidity preventing unit is implemented on an inner sidewall of the sealing cover to absorb humidity. The buffer layer increases strength of the sealant and an adhesion between the substrate and the sealing cover. |
