An organic light-emitting display apparatus that has reduced resonance effect includes a thin film transistor (TFT) layer including a plurality of TFTs, first protective layer covering the TFT, a color filter disposed in at least a partial area of the region in the first protective layer, a first overcoat covering the color filter, a second protective layer covering the first overcoat, a second overcoat disposed on the second protective layer, and a pixel electrode disposed on top of the second overcoat and electrically coupled to the TFTs in the TFT layer.
