Display apparatus

A display apparatus comprising:

• a substrate including a display area and a peripheral area surrounding the display area;
• display elements arranged in the display area;
• and
• a thin film encapsulation layer covering the display area, the thin film encapsulation layer comprising an inorganic encapsulation layer, an organic encapsulation layer, and a composite encapsulation layer sequentially stacked on one another,
• wherein the composite encapsulation layer comprises a plurality of sub-layers stacked on each other and a thickness of the composite encapsulation layer is less than a thickness of the inorganic encapsulation layer, wherein at least one sub-layer of the plurality of sub-layers includes an organic-inorganic hybrid material.

A flexible display apparatus comprising:

• a flexible substrate including a display area and a peripheral area surrounding the display area;
• display elements arranged in the display area;
• a spacer disposed between the display elements, the spacer including a lateral side having a first slope;
• and
• a thin film encapsulation layer covering the display area, the thin film encapsulation layer including a buffer encapsulation layer disposed above the display area and an inorganic encapsulation layer disposed above the buffer encapsulation layer, the buffer encapsulation layer comprising an organic-inorganic hybrid material;
• wherein an upper surface of the buffer encapsulation layer has a second slope that is smaller than the first slope, the second slope overlapping the first slope in a direction of a thickness of the substrate.
