Organic electroluminescent device |
摘要 |
An EL device according to the invention comprises a seal of an organic sealing material which substantially does not extend inside the inner perimeter 8 of the sealing surface. To be able to provide the sealing material between the sealing surfaces by capillary action, the seal has a thickness of less than 100 micrometers. Preferably, the seal has a thickness of less than 10 micrometers and a width of more than 0.2 mm, so that the diffusion of volatile materials through the seal is greatly reduced.
