Document Type and Number:
WIPO Patent Application WO/2019/128032
Kind Code:
A1
Abstract:
The invention relates to the field of display technology, and a package structure, a preparation method thereof and an organic electroluminescence device are disclosed. The package structure comprises: a first substrate and a second substrate arranged opposite to each other; a to-be-packaged body formed in between the first substrate and the second substrate; a packaging layer formed on the first substrate and continuously covering an exposed surface of the to-be-packaged body; and a desiccant layer arranged in between the packaging layer and the second substrate in a sandwiched manner, wherein the desiccant layer is in a gel state. According to the invention, the desiccant layer in the gel state is formed in between the packaging layer and the second substrate by curing the liquid desiccant, and there is no requirement for the thickness of the desiccant layer. Therefore, the water and oxygen barrier capability of the package structure can be increased without increasing the thickness of the package structure.
