Display apparatus and method of manufacturing the same

A display apparatus comprising:

• a base substrate;
• a first conductive layer disposed on the base substrate, wherein the first conductive layer includes a source electrode and a drain electrode of a thin film transistor;
• a first via insulating layer disposed on the first conductive layer;
• a second conductive layer disposed on the first via insulating layer;
• a second via insulating layer disposed on the second conductive layer;
• a pixel-defining layer disposed on the second via insulating layer;
• a first inorganic layer disposed on the pixel-defining layer;
• and
• an organic layer disposed on the first inorganic layer,
• wherein a portion of the second via insulating layer and a portion of the pixel-defining layer constitute a first dam,
• a portion of the second via insulating layer and a portion of the pixel-defining layer constitute a first stacked structure having a height less than a height of the first dam, and
• the organic layer overlaps a substantially entire portion of the first stacked structure and at least a portion of the first dam.

A method of manufacturing a display apparatus including a display area for displaying an image and a non-display area adjacent to the display area, the method comprising:

• providing a thin film transistor layer, which includes a thin film transistor and an insulating layer, on a base substrate;
• providing a first via insulating layer on the thin film transistor layer;
• providing a conductive layer, which includes a power supply wire, on the first via insulating layer;
• providing a second via insulating layer on the first via insulating layer, on which the conductive layer is provided;
• providing a first inorganic layer on the base substrate, on which the second via insulating layer is provided;
• providing an organic material onto the first inorganic layer;
• and
• inspecting a spreading degree of the organic material which spreads along a top surface of the first inorganic layer based on a visibility degree of an outer periphery of a first stacked structure,
• wherein a portion of the second via insulating layer constitutes a first dam disposed in the non-display area to surround the display area, and
• a portion of the second via insulating layer constitutes the first stacked structure disposed between the first dam and the display area in the non-display area.
