  • Patent number: 10199599
    Abstract: An organic light emitting diode device can have an enhanced thin film encapsulation layer for preventing moisture from permeating from the outside. The thin film encapsulation layer can have a multilayered structure in which one or more inorganic layers and one or more organic layers are alternately laminated. A barrier can be formed outside of a portion of the substrate on which the organic light emitting diode is formed. The organic layers of the thin film encapsulation layer can be formed inside an area defined by the barrier.
