Abstract: A foldable display apparatus includes a display panel, a cover window on the display panel, and a first layer between the display panel and the cover window, the first layer having a storage modulus lower than a storage modulus of the cover window to reduce durability defects in the apparatus. The apparatus may further include a protective part between the display panel and the cover window for distributing stress and further reducing durability defects.

Abstract: A display apparatus includes a display panel part, a polarizing member, and a neutral plane compensation member disposed between the display panel part and the polarizing member. The neutral plane compensation member includes a first layer and a second layer, a thickness of the first layer being in a range of 20 μm to 60 μm, and a modulus of elasticity of the first layer being in a range of 1×108 Pa to 1×1010 Pa, a thickness of the second layer being in a range of 20 μm to 60 μm, and a modulus of elasticity of the second layer being in a range of 1×104 Pa to 1×106 Pa.
