1. An organic light emitting display apparatus comprising:
a substrate;
a pixel array layer provided on the substrate, the pixel array layer including a thin film transistor and a light emitting diode;
an encapsulation layer covering the pixel array layer; and
a metal encapsulation substrate provided on the encapsulation layer,
wherein the metal encapsulation substrate includes a first portion including a first member and a second portion including at least a plurality of second members, and
wherein a top surface of the metal encapsulation substrate includes a top surface of the first portion and a top surface of the second portion, and wherein the plurality of second members at least in part overlaps with the light emitting diode of the pixel array layer in a direction vertical with respect to the top surface of the metal encapsulation substrate.
