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.
