Title:
PROTECTING MEMBER, AND ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/219957
Kind Code:
A1
Abstract:
An organic EL display device 1 comprises, in this order, an organic EL panel member 4, a first adhesive layer 16, a substrate 17, a second adhesive layer 18, and a metal plate 6. In a case (1) in which a tensile modulus E of the substrate 17 is at least equal to 1 GPa and less than 5 GPa, the tensile modulus E of the first adhesive layer 16 is at least equal to 0.03 MPa and less than 0.15 MPa. In a case (2) in which the tensile modulus E of the substrate 17 is at least equal to 5 GPa and less than 10 GPa, the tensile modulus E of the first adhesive layer 16 is at least equal to 0.03 MPa and less than 0.15 MPa or the tensile modulus E of the second adhesive layer 18 is at least equal to 0.03 MPa and less than 0.15 MPa. In a case (3) in which the tensile modulus E of the substrate 17 is 10 GPa to 15 GPa inclusive, the tensile modulus E of the second adhesive layer 18 at 25°C is 0.03 MPa to 0.15 MPa inclusive.
