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.
