Abstract
A display apparatus including a substrate; an organic EL device including an electrodewhich is formed on the substrate, an organic EL layerwhich is formed on the electrode, and an electrodewhich is formed on the organic EL layer; an inorganic insulating filmwhich is formed on the organic EL device, sealing the organic EL layer; and a substratewhich is formed on the inorganic insulating film, wherein the material and the thickness of the substrateand the substrateare set such that the neutral axis when a bending stress is applied is located in the vicinity of the interface between the inorganic insulating filmand the substrate. By configuring such a display apparatus, occurrence of cracks in the inorganic insulating film is prevented, and the organic EL device can be effectively protected against moisture and oxygen. As a result, the reliability of the display apparatus can be improved.
