Abstract:
An organic light emitting display apparatus includes: 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, including an organic emission layer; a counter electrode covering the intermediate layer; an external light reflection layer disposed on the counter electrode, the external light reflection layer being configured to reflect a portion of incident visible rays; and absorb and transmit another portion of the incident visible rays; a phase control layer disposed between the counter electrode and the external light reflection layer, being configured to control a phase of a light reflected by the counter electrode to destructive 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.
