Flexible display apparatus

A flexible display apparatus, comprising:

• a display substrate having an active area on which an image is displayed, a bending area extending outward from the active area and that is bendable in one direction, and an edge area extending outward from the bending area;
• a thin film encapsulation (TFE) layer on the display substrate and including a first inorganic layer, an organic layer, and a second inorganic layer, the first inorganic layer and the second inorganic layer extending from the active area to the edge area;
• a thin film transistor (TFT) on the display substrate and including a semiconductor active layer, a gate electrode, a source electrode, and a drain electrode;
• an organic light-emitting device (OLED) on the display substrate and including a first electrode, an organic emissive layer, and a second electrode;
• a pixel defining layer comprising an organic material and covering an edge of the first electrode;
• a spacer on the pixel defining layer;
• an insulating protective film disposed directly at a bottom surface of the first electrode, covering the source electrode and the drain electrode of the TFT, and insulating the TFT from the OLED;
• and
• at least one insulating dam on the display substrate,
• wherein the at least one insulating dam is in the edge area,
• wherein the at least one insulating dam includes a plurality of layers, the plurality of layers including a first layer formed of a same material as the insulating protective film, a second layer formed of a same material as the pixel defining layer, and a third layer formed of a same material as the spacer,
• wherein the insulating protective film and the first layer of the at least one insulating dam formed of the same material as the insulating protective film are both directly on an interlayer insulating film that is away from the first electrode and covers the gate electrode of the TFT, and
• wherein the first inorganic layer and the second inorganic layer cover an outer surface of an outermost dam of the at least one insulating dams.
