1. A display apparatus comprising:

  • a first substrate;

    an organic EL device comprising a first electrode which is formed on said first substrate, an organic EL layer which is formed on said first electrode, and a second electrode which is formed on said organic EL layer;

    a first inorganic insulating film which is formed on said organic EL device, sealing said organic EL layer; and

    a second substrate which is formed on said first inorganic insulating film,wherein the material and the thickness of said first substrate and said second substrate are set such that the neutral axis when a bending stress is applied is located in the vicinity of the interface between said first inorganic insulating film and said second substrate, andwherein the rigidity of said first substrate and the rigidity of said second substrate are identical to each other.
