Abstract: A display device, including a folding region, and first and second non-folding regions at opposing sides of the folding region, includes: a display module; a support member on the display module; and a bonding layer between the display module and the support member. The support member includes a first support member in the first non-folding region and a part of the folding region, and a second support member in the second non-folding region and a part of the folding region. The bonding layer is over the folding region and the first and second non-folding regions. The bonding layer includes first to third portions in the first non-folding region, in the second non-folding region, and in the folding region, respectively. Adhesive force of the first portion to the support member is less than adhesive force of the second portion to the first support member or the second support member.
