Abstract: A thin-film encapsulation structure includes a number of inorganic film layers and at least one organic film layer laminated alternately at one side of an organic light-emitting diode. The number of inorganic film layers include N inorganic film layers including first to N-th inorganic film layers arranged sequentially from inside to outside, N≥2. At least the first inorganic film layer has a refractive index increasing gradually from inside to outside.
