Display apparatus and method of manufacturing the same

A display apparatus, comprising:

• a base substrate;
• a thin film transistor disposed on the base substrate, and including an active pattern and a gate electrode;
• an electrode electrically connected to the thin film transistor;
• a gate insulating layer disposed between the active pattern of the thin film transistor and the gate electrode;
• a first insulating layer disposed on the thin film transistor and the electrode;
• a second insulating layer disposed on the first insulating layer;
• and
• an insulating layer disposed between the first insulating layer and the second insulating layer and in direct contact with the first insulating layer and the second insulating layer, and
• wherein Young's modulus of the insulating layer is equal to or greater than about 70 gigapascals.

A method of manufacturing a display apparatus, the method comprising:

• forming a thin film transistor on a base substrate, an electrode electrically connected to the thin film transistor and a thin film transistor insulating layer;
• forming a first organic insulating layer on the thin film transistor and the thin film transistor insulating layer;
• defining a first contact hole exposing the electrode in the first organic insulating layer;
• forming an insulating layer on the first organic insulating layer in which the first contact hole is defined;
• defining an opening through the insulating layer to expose the first contact hole;
• forming a second organic insulating layer on the insulating layer and the first organic insulating layer in which the opening is defined;
• and
• defining a second contact hole exposing the electrode through the second organic insulating layer.
