Abstract: A display device includes a window, a display module, a protection film, a circuit board, a first area adhesive member, and a second area adhesive member. The window includes a first area providing a front surface and a second area bent from the first area to provide a side surface. The display module includes a first portion coupled to the window and a second portion extending from the first portion. The protection film includes a first film portion corresponding to the first portion and a second film portion corresponding to the second portion, and is disposed below the display module. The first area adhesive member couples the first portion and the first film portion. The second area adhesive member couples the second portion and the second film portion, and has an elastic modulus greater than that of the first area adhesive member. The circuit board is coupled to the second portion.

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 display panel, a first protective member, and a second protective member. The display panel includes a front part, a first side part extending from the front part, and a pad portion extending from the first side part. A pad is on the pad portion, the first side part is bent, and each of the front part and the first side part displays an image. The first protective member is below the display panel and overlaps the front part and the first side part. The second protective member is below the display panel, in a same layer as the first protective layer, and overlaps the pad portion. The second protective member has a bending stiffness greater than a bending stiffness of the first protective member.
