A structure and a method for packaging an organic optoelectronic device are provided. In this method, a first substrate is provided, and a first barrier layer is disposed on the first substrate. An organic optoelectronic device is formed on the first barrier layer, and a first recess is also formed on the first barrier layer, in which the first recess forms a closed loop to surround the organic optoelectronic device. A sealant fills the first recess, and a second barrier layer is disposed on the organic optoelectronic device, in which the sealant attaches the second barrier layer to the first barrier layer to surround the organic optoelectronic device.
