RESIN LAYER, OPTICAL FILM, AND IMAGE DISPLAY DEVICE

WIPO Patent Application WO/2020/179643

A1

Provided are a resin layer having good foldability and good impact resistance, and an optical film and an image display device provided with the same. One embodiment of the present invention provides a light-transmissive resin layer 10 for use in an image display device, wherein when the resin layer 10 is divided in the thickness direction D1 of the resin layer 10 into three equal parts of a first region 10C, a second region 10D, and a third region 10E in this order from a first surface 10A of the resin layer 10 to a second surface 10B on the opposite side of the resin layer 10 from the first surface 10A, the resin layer 10 satisfies the relationship d1 < d2 < d3, where d1, d2, and d3 are the amount of displacement in the first region 10C, the amount of displacement in the second region 10D, and the amount of displacement in the third region 10E, respectively, which are determined by a pressing test in which a Berkovich indenter is pressed, with a predetermined load, into each of the first region 10C, the second region 10D, and the third region 10E in a cross section of the resin layer 10 in the thickness direction D1.
