摘要: According to one aspect of the present invention, a light-transmitting resin layer used in an image display device is provided, in which the layer is divided into three equal parts in the film thickness direction of the layer, which are referred to as first region, second region, and third region, respectively, in the order from a first surface of the layer to a second surface opposite to the first surface. Upon an indentation test in which a Berkovich indenter is pressed into the first region, the second region, and the third region at a certain load on the cross-section of the layer in the film thickness direction, and in which the displacement amount in the first region, in the second region, and in the third region are determined as d1, d2, and d3, respectively, the layer satisfies the relationship of d1
