Adhesive layer-equipped transparent surface material, display device and processes for their production

An adhesive layer comprising:

• a cured product of a composition which comprises a curable component and a non-curable oligomer,
• wherein:
• the curable component comprises a curable oligomer which comprises a curable group and a urethane bond,
• the non-curable oligomer comprises a hydroxy group and does not undergo a curing reaction with the curable component,
• the non-curable oligomer has a number average molecular weight per one hydroxy group of from 400 to 8,000,
• the number of hydroxy groups per one molecule of the non-curable oligomer is from 1.8 to 3,
• the curable oligomer and the non-curable oligomer comprise:
• a same repeating unit comprising a polyoxyalkylene structure;
• or
• repeating units derived from a same monomer comprising a polyoxyalkylene structure,
• a content of the non-curable oligomer is from 10 to 70 mass % in a total of the composition, and
• the adhesive layer has a shear modulus at 35° C. of from 0.5 to 100 kPa.
