Abstract: A display device includes: a display panel including a front surface and a rear surface, the rear side being opposite to the front side; a front stacked structure on the front surface including a front bonding member disposed on the front surface; and a rear stacked structure on the rear surface including a rear bonding member disposed on the rear surface. A loss tangent of the front bonding member has a value greater than a loss tangent of the rear bonding member, the loss tangent being represented by an equation: (loss tangent)=(loss modulus)/(storage modulus), wherein the loss modulus refers to energy lost by viscosity of a material, and the storage modulus refers to energy stored without loss by elasticity of the material.

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.
