Claim:
1. An organic light emitting display apparatus comprising: a substrate divided into an emission area and a non-emission area; a pixel electrode disposed in the emission area; an intermediate layer disposed on the pixel electrode, the intermediate layer comprising an organic emission layer; a counter electrode disposed in the emission area and the non-emission area, the counter electrode covering the intermediate layer; an external light reflection layer disposed on the counter electrode in the emission area and the non-emission area, the external light reflection layer being configured to: a phase control layer disposed between the counter electrode and the external light reflection layer, the phase control layer being configured to control a phase of light reflected by the counter electrode to destructively interfere with light reflected by the external light reflection layer; a thin-film encapsulating layer disposed on the external light reflection layer; and a black matrix disposed on the thin-film encapsulating layer in the non-emission area.
