<P>PROBLEM TO BE SOLVED: To provide an adhesive sheet for optical use with a lower dielectric constant and without white turbidity by humidification, and to provide the adhesive sheet for optical use, excellent also in corrosion resistance. <P>SOLUTION: The adhesive sheet for optical use has an adhesive layer with a relative dielectric constant of four or less at frequency 100 kHz, and a moisture percentage of 0.65% by weight or more after being preserving for 120 hours under the environment of 60°C and 95%RH. Preferably, the adhesive sheet for optical use has total light transmittance of 90% or more, and haze of 3% or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
