Organic light-emitting display apparatus and method of manufacturing the same

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

• a first process comprising forming a semiconductor layer on a substrate, patterning the semiconductor layer, and then forming an active layer of a thin film transistor;
• a second process comprising forming a first insulating layer, forming a first metal layer on the first insulating layer, and patterning the first metal layer to form a gate electrode of the thin film transistor and a first electrode of a capacitor;
• a third process comprising forming a first interlayer insulating layer, forming a semi-transmissive metal layer on the first interlayer insulating layer, and patterning the semi-transmissive metal layer to form a pixel electrode;
• a fourth process comprising forming the first interlayer insulating layer and forming an aperture in the first interlayer insulating layer to expose a portion of the active layer;
• a fifth process comprising forming a second interlayer insulating layer and patterning the second interlayer insulating layer to form apertures respectively exposing the portion of the active layer, an upper portion of the pixel electrode, and the first interlayer insulating layer corresponding to the first electrode of the capacitor;
• a sixth process comprising forming a second metal layer and a protection layer, and patterning the second metal layer and the protection layer to form a source electrode, a drain electrode, a second electrode of the capacitor, and a pad electrode;
• and
• a seventh process comprising forming a first organic layer and patterning the first organic layer to form apertures respectively exposing an upper portion of the pixel electrode and an upper portion of the pad electrode.
