Abstract

An encapsulated film and a method for encapsulating luminescent device, and a luminescent device, the encapsulated film includes N laminated units, each of the laminated units is composed of barrier layers and surfactant layers which are arranged to be sequentially laminated, the barrier layers and the surfactant layers alternate so that they are adjacent to each other in the encapsulated film, wherein N is an integer greater than or equal to 1. By using the encapsulated film to encapsulate the luminescent device, erosion of water-oxygen to a functional layer of the luminescent device can be effectively reduced, and a service life of the luminescent device is improved.
