Barrier structure

[0017]The present invention provides a barrier structure for covering at least a part of an object for protecting the object from gas and water in an external environment. The barrier structure comprises a first condensed matter layer, which has a first surface and a second surface, and a second condensed matter layer contacting the second surface. The first surface directly contacts the external environment. The first condensed matter layer is penetrable by at least one type of gas. An interface is formed between the second surface of the first condensed matter layer and the second condensed matter layer for protecting the object from the water and the gas in the external environment. The barrier structure can be applied to a component in an electronic product, food, medicine, or the object in which barrier characteristic is required against the external environment. The electronic product may be an organic light emitting diode, a flexible liquid crystal display, an electronic paper,
