PHOTOCURABLE ADHESIVE SHEET

WIPO Patent Application WO/2022/045130

A1

The purpose of the present invention is to provide an adhesive sheet which exhibits superior conformability and workability, and is suited for producing emissive display devices such as mini/micro LED display devices which have an improved contrast and a function for preventing reflection from metallic wiring and the like. A photocurable adhesive sheet according to the present invention is characterized in that: the photocurable adhesive sheet includes an adhesive agent layer that is cured by irradiation; the adhesive agent layer includes a colorant; the adhesive agent layer has a maximum value for the transmittance of wavelengths in the range of 200-400 nm which is greater than the maximum value for the transmittance of wavelengths in the range of 400-700 nm; the storage modulus (G'b85) of the uncured adhesive agent layer at 85°C is less than 65 kPa; and the storage modulus (G'a10) of the cured adhesive layer at 10°C and the storage modulus (G'b85) of the uncured adhesive layer at 85°C satisfy relational expression (1).　Relational Expression (1): 3.3
