Abstract:
The present invention is intended to provide an optical laminate that achieves a superior film strength and a property that a void-provided layer and a pressure-sensitive adhesive/adhesive layer are not easily peeled from each other. The optical laminate of the present invention includes: a void-provided layer; an intermediate layer; and a pressure-sensitive adhesive/adhesive layer, wherein the void-provided layer, the intermediate layer, and the pressure-sensitive adhesive/adhesive layer are stacked in this order, and the intermediate layer is formed by forming the pressure-sensitive adhesive/adhesive layer on the void-provided layer.
