Abstract: A display apparatus includes a substrate having a display area and a peripheral area surrounding the display area. Display elements are arranged in the display area. A spacer is disposed between the display elements and includes a lateral side having a first slope. A thin film encapsulation layer covers the display area and includes a buffer encapsulation layer, an inorganic encapsulation layer, an organic encapsulation layer, and a composite encapsulation layer sequentially stacked on one another. The composite encapsulation layer includes a plurality of sub-layers stacked on each other. Each of the sub-layers has a thickness that is less than a thickness of the inorganic encapsulation layer. An upper surface of the buffer encapsulation layer has a second slope that is smaller than the first slope. The second slope overlaps the first slope in a direction of a thickness of the substrate.

Abstract: A display device includes: a first substrate having a main region, a pad area, and a bending area therebetween; and a second substrate on the main and pad regions of the first substrate opposite to a side where a thin film transistor layer is arranged. The second substrate includes a first sub-substrate overlapping the main region and a second sub-substrate spaced apart from the first sub-substrate with the bending area therebetween and overlapping the pad area. The first sub-substrate has: a first surface facing the first substrate; a second surface opposite to the first surface; a first inclined surface facing the bending area and extending to the first surface; and a second inclined surface extending between the second surface and the first inclined surface. The first surface has an uneven structure.
