Organic light-emitting display apparatus

An organic light-emitting display apparatus comprising:

• a substrate;
• a display portion on the substrate and comprising an organic light-emitting device;
• a non-display portion being a peripheral region of the display portion on the substrate;
• an encapsulation layer on the display portion and comprising a first, first encapsulation layer on the display portion, a first, second encapsulation layer on the first, first encapsulation layer, and a second, first encapsulation layer on the first, second encapsulation layer;
• and
• a light function layer directly contacting the display portion, the light function layer being separate from the encapsulation layer and arranged between the display portion and the encapsulation layer, the light function layer for reflecting ultraviolet light and having a thickness of less than 150 nm,
• wherein an end portion of the first, first encapsulation layer contacts the substrate and an end portion of the second, first encapsulation layer contacts the end portion of the first, first encapsulation layer,
• wherein each of the first, first encapsulation layer and the second, first encapsulation layer is composed of an inorganic material and the first, second encapsulation layer is composed of an organic material, wherein the light function layer is a single layer, and wherein the light function layer comprises a material selected from the group consisting of Alq3, benzophenone, photo acryl, BaF2, CsF, NasA13F14, KC1, and combinations thereof.
