Summary: | The purpose of the present invention is to provide an optical adhesive tape for maintaining an excellent appearance of a tiling display in which a plurality of image display devices are aligned in a tile shape, the optical adhesive tape being capable of maintaining transparency and preventing gaps between the plurality of image display devices from being conspicuous, even in a usage environment. The optical adhesive tape 10A of the present invention has a laminated structure in which are laminated: a base material 1 having a first surface 1a and a second surface 1b; and an adhesive layer 2 laminated to the first surface 1a of the base material 1. A mean dimensional change rate in a transverse direction and a machine direction, when the optical adhesive tape 10A is heated for 500 hours in an environment with a temperature of 60 DEG C and a relative humidity of 90%, is within ±0.15%. A 300% tensile residual stress value of the adhesive layer 2 is 10 N/cm2 or less. |
