Organic light-emitting display apparatus having a light-scattering face and method of manufacturing the same

An organic light-emitting display apparatus comprising:

• a substrate;
• a first electrode on the substrate;
• a pixel-defining layer (PDL) on the first electrode to expose a region of the first electrode;
• an intermediate layer in the exposed region of the first electrode and comprising an organic emission layer;
• a second electrode having a light-scattering face facing the substrate or facing oppositely away from the substrate, the second electrode being on the intermediate layer;
• and
• an insertion layer on the intermediate layer and the PDL, wherein:
• the second electrode is on an upper surface of the insertion layer, the insertion layer comprises an uneven face, and
• the light-scattering face contacts the uneven face of the insertion layer.

A method of manufacturing an organic light-emitting display apparatus, the method comprising:

• forming a first electrode on a substrate;
• forming a pixel-defining layer (PDL) on the first electrode to expose a region of the first electrode;
• forming an intermediate layer on the exposed region of the first electrode, the intermediate layer comprising an organic emission layer;
• and
• forming a second electrode, the second electrode having a light-scattering face facing the substrate or facing oppositely away from the substrate,
• wherein a surface of the intermediate layer facing the first electrode is smooth.
