Abstract:
A device with light emitting elements can prevent interfacial peeling of a plurality of layers. The device with light emitting elements includes: a substrate including an emission area in which the light emitting elements are arranged and a non-emission area that surrounds the emission area; a first organic film that covers the emission area and has a first modulus of elasticity; a second organic film that is disposed on the first organic film and has a second modulus of elasticity which is greater than the first modulus of elasticity; and a metal film that is disposed on the second organic film and has a third modulus of elasticity which is greater than the second modulus of elasticity.
