Assembly layer for flexible display

A method of adhering a first substrate and a second substrate, wherein both of the first and the second substrates are flexible, the method comprising:

• positioning an assembly layer between the first flexible substrate and the second flexible substrate to form a laminate, wherein within a temperature range of between about −30° C. to about 90° C., the assembly layer has a shear storage modulus at a frequency of 1 Hz that does not exceed about 2 MPa, a shear creep compliance (J) of at least about 6×10−6 1/Pa measured at 5 seconds with an applied shear stress between about 50 kPa and about 500 kPa, and a strain recovery of at least about 50% at at least one point of applied shear stress within the range of about 5 kPa to about 500 kPa within about 1 minute after removing the applied shear stress, wherein the assembly layer comprises at least one of a polyisoprene, a polybutadiene, an olefin block copolymer, a polyisobutylene, and high alkyl polyolefin;
• and
• applying at least one of pressure and heat to form a laminate.
