A display device includes a first substrate, a second substrate, a first auxiliary substrate, a second auxiliary substrate, and a display layer. The second substrate includes a display area and a non-display area. The display area overlaps the first substrate. The non-display area extends beyond the first substrate. The first auxiliary substrate includes a first section and a second section. The first section is between the first substrate and the display area. The second section overlaps the non-display area and is bent relative to the first section. The second auxiliary substrate includes a first part and a second part. The first part is between the first section and the display area. The second part overlaps the non-display area and is bent relative to the first part. The display layer is between the first section and the first part and includes pixels that overlap the display area.
