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