A1
Abstract:
A base resin substrate layer (10), an organic EL element layer (20), a ground layer (28), and a hard coat layer (29) constituting part of an organic EL display device (100aa) have residual strain ratios κ1, κ2, κ3, and κ4 respectively, have thickness d1, d2, d3, and d4 respectively, have Young's modulus E1, E2, E3, E4 respectively, and have stress distribution coefficient α1, α2, α3, and α4,respectively. The relational expression (κ1α1d1/E1 + κ2α2d2/E2 + κ3α3d3/E3 + κ4α4d4/E4) ≤ 0.4 µm is satisfied, where σ is the pressure applied to the surface of the hard coat layer (29).
