Abstract
An organic light-emitting display apparatus includes: a substrate; a pixel electrode disposed on the substrate; a counter electrode disposed on the pixel electrode and capable of transmitting light; an organic emission layer disposed between the pixel electrode and the counter electrode so as to emit light toward at least the counter electrode; and a light-transmitting layer disposed on the counter electrode along a path of light emitted from the organic emission layer and including at least one inorganic film and organic films separated by the inorganic film. At least two of the organic films each include a first material having a first refractive index and a second material having a second refractive index. The first refractive index is greater than the second refractive index, and the first material is dispersed in the second material in the form of plurality of particles.
