Abstract
The invention relates to an organic optoelectronic device, such as a display, lighting or signalling device, that is protected from the ambient air by a sealed encapsulation in the form of a thin film, and to a method for encapsulating such a device. An optoelectronic device () according to the invention is coated with a sealed multi-layer encapsulation structure () comprising alternating inorganic layers (to) and organic layers (to). According to the invention, the device is such that at least one of said organic layers consists of a crosslinked adhesive film (to) based on a glue that can be crosslinked thermally or by electromagnetic radiation, the or each adhesive film having a thickness uniformly lower than 200 n, said thickness being obtained by passing the film, which is deposited and not yet cross-linked, through a vacuum, such that the total thickness of the encapsulation structure is minimized.
