Abstract: A display device includes a flexible base layer including a first portion and a second portion. A display unit is disposed on a first surface of the first portion. The display unit includes a light emitting element. A driving circuit is disposed on a first surface of the second portion. The driving circuit includes a driving chip. A first support member is disposed on a second surface of the first portion opposite the first surface. A second support member is disposed on a second surface of the second portion. The second support member includes a first opening overlapping the driving circuit. The second surface of the second portion is on an opposite side of the second portion from the first surface of the second portion. A first reinforcing member is disposed in the first opening. The first reinforcing member includes a different material from the second support member.
