Abstract
An organic light-emitting display device includes: a substrate; a first organic light-emitting layer disposed on the substrate; a pixel defining film disposed on the first organic light-emitting layer and having a first opening, which at least partially exposes the first organic light-emitting layer; and an optical path converter disposed on the pixel defining film to overlap with the first organic light-emitting layer and including a first optical path converting member, which has a first refractive index, and a second optical path converting member, which has a second refractive index that is lower than the first refractive index.
