Claim:
A display apparatus comprising: a display panel; a driving circuit board arranged to drive the display panel; a front side viscoelastic layer that is viscoelastic and arranged to cover a display surface of the display panel; a front side hard layer that has a higher modulus of elasticity than the front side viscoelastic layer, and is arranged to cover the front side viscoelastic layer; a back side viscoelastic layer that is viscoelastic, and is arranged to cover a back surface of the display panel; a back side hard layer that has a higher modulus of elasticity than the back side viscoelastic layer, and is arranged to cover the back side viscoelastic layer; and a rigid plate made of rigid material having a plane surface, which is provided on a back side of the back side hard layer; wherein the back side viscoelastic layer has a thickness Tb of not less than about 20 μm, and the front side viscoelastic layer has a thickness Ta and satisfying: Ta/Tb> 1( Tb≠ 0).
