Display apparatus and method of manufacturing the same

A method of manufacturing a display apparatus including a display area including a plurality of sub-pixels and a non-display area outside the display area, the method comprising:

• forming a thin film transistor positioned on a substrate of the display area, and a first wiring and a second wiring positioned on the substrate of the non-display area;
• sequentially forming a first insulating layer and a second insulating layer on the thin film transistor, the first wiring, and the second wiring, and forming a first opening overlapping the thin film transistor and a second opening between the first wiring and the second wiring in the second insulating layer using a halftone mask;
• using the first opening and the second opening, respectively, to form a third opening extending from the first opening and a fourth opening extending from the second opening and penetrating through the first insulating layer;
• forming a sub-pixel electrode overlapping the first opening and the third opening and electrically connected to the thin film transistor, and a photoresist pattern on the sub-pixel electrode, and removing a portion of the second insulating layer in an area not overlapping the photoresist pattern using the photoresist pattern as an etching mask;
• and
• sequentially forming a light-emitting layer, an opposite electrode, and an encapsulation layer on the sub-pixel electrode, and removing the second insulating layer positioned in an area not overlapping the encapsulation layer using the encapsulation layer as an etching mask.
