  • ADHESIVE FILM, ADHESIVE LAYER-EQUIPPED TRANSPARENT PLATE AND DISPLAY DEVICE
    Publication number: 20200247095
    Abstract: To provide an adhesive film by which air bubbles formed at a bonding interface when the adhesive film is used for bonding, readily disappear under normal temperature and normal pressure. One embodiment of the adhesive film of the present invention is characterized by having at least one adhesive layer, wherein the adhesive layer satisfies the following requirements (a) to (c). (a) A diffusion coefficient of nitrogen gas is at least 1.5×10?6 cm2/sec, (b) A shear modulus G? (1 Hz) is from 5×102 to 1.0×105 Pa, at a measurement temperature of 25° C. and a frequency of 1 Hz, and (C) The adhesive layer has an absorption peak at from 800 to 820 cm?1 and no absorption peak at from 1,000 to 1,020 cm?1, in an infrared absorption spectrum.
