An organic light emitting device, and the passivation layer of an organic light emitting device

An organic light emitting device includes a first substrate (100); a thin film transistor layer (200) formed on the first substrate (100); a light-emitting diode layer (300) formed on the thin film transistor layer (200); and forming a passivation layer (500) on the light emitting diode layer (300), wherein the passivation layer (500) comprises a first inorganic insulating film (510) and a second inorganic insulating film (520), wherein a (in the first inorganic insulating film 510 ) contained hydrogen content is less than the proportion of hydrogen contained (in the second inorganic insulating film 520).
