An organic light-emitting display apparatus includes: a substrate; a 1-1pixel electrode in a 1-1pixel to emit light of a first wavelength range and a 1-2pixel electrode in a 1-2pixel to emit light of the first wavelength range. The 1-1pixel and the 1-2pixel are over the substrate; a pixel-defining layer covering an edge of the 1-1pixel electrode and an edge of the 1-2pixel electrode so as to define a 1-1exposed upper surface and a 1-2exposed upper surface; a 1-1emission layer over the 1-1pixel electrode and to generate the light of the first wavelength range and a 1-2emission layer over the 1-2pixel electrode and to generate the light of the first wavelength range; and an opposite electrode over the 1-1emission layer and the 1-2emission layer.
