Abstract:
The present invention relates to an encapsulation cap, an organic electroluminescent device having the same, and a manufacture method thereof.The encapsulation cap protects each of elements in a device formed on a substrate from outside, comprising a sealing surface adhering to the substrate , wherein at least one groove is formed at an edge of the sealing surface.The encapsulation cap protecting each of elements in a device formed on a substrate from outside comprises a sealant surface adhering to the substrate and a holding part holding each of elements of the device, wherein a concave part is formed on the sealant surface along an edge that the sealing surface and the holding part meet.The encapsulation cap, the organic electroluminescent device having the same, and the manufacturing method thereof according to the present invention can prevent overflowing of a sealant because of the structure capable of holding extra-sealant applied to the sealing surface.
